• (2024-02-26) Mike Fireson: This is great extension! But now I every time get crash DB, I delete old DB, import backups and after chrome restart and addon open have message about crash DB, and every time, I delete and import DB 5 times and every time this error, why??? (((((
• (2024-01-23) Chahjadi Jong: Very useful extension to look back the pages that I've visited a long time ago. I've been using it since 2021, the extension is also well maintained. 2024 Edit: Developer is very helpful, and willing to help over email.
• (2023-12-22) Omar Hammad: I absolutely love this extension. From the moment you start using it, it archives your entire history and even displays it clearly for future reference versus the vague text documents other programs may be limited to. I just wish I started using it 10 years ago, but I at least still have from 2015 onward. The ability to export in full or in increments and then import it all later even ensures the longevity of the history in case of accidents. Edit: I'll keep the rating decent, but I must mention that it is now inconvenient to use this extension due to regular data corruption. It's the fault of Google, but it's still a negative. Also, for users who had .tsv backups like me, be sure to change the extension to .txt and they will import.
• (2023-12-09) Sebastián Poëymirou: With the corruption thing going on does that mean that all the history I haven't backuped is gone? :(
• (2023-11-24) Александр Марков: Theres restriction for saving history data, its about 1gb. After that number an error appears and extension dont work. I had four years of history backed up and now I had to start with a clean slate to make extension work fine.
• (2023-11-14) Liam: Is uninstalling the extension then reinstall the only way to fix "database disk image is malformed" error? 21/10/2023 1: Can i import data from Google's My Activity 21/10/2023 2: Can i easily delete the extension' current history without uninstalling?
• (2023-11-04) Greg D: About once a month, this extension's local database fails and I have to uninstall it, reinstall it, and import my history (which takes like 15 minutes). This has happened 3 separate times since the SQLite migration.
• (2023-11-04) Phoppon Munjai: Hello randy after the database change i did upload new history from back up it work just fine but today it say Error: SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed edited: i just read faq nvm reinstall extension and import history again seem to be working fine now after remove some extension
• (2023-11-03) Alexandra Del: I think I saved all my history as exported_analysis_history. It's a year and a half old and dated, but there just seems to be no way to load "Unrecognized return value from import-worker". Is there any way?
• (2023-10-26) S L: Incredible extension! Thank you so much
• (2023-10-25) Lâm Nguyễn: Please help me "database disk image is malformed" so I uninstalled and reinstall work fine for a couple of weeks then the same error again
• (2023-10-23) Mike Butt: Imported 3 urls and 3 visits Errors: 1,081,429 lines could not be imported
• (2023-10-21) Komet: I have been using this extension for over 10 years, because I occasionally needed to re-visit websites from months or even years ago, and the standard search would only keep entries for a few weeks. With History Search Unlimited, I could search for both URL and title and even now it is still actively maintained, so thank you!
• (2023-10-20) Chuck Colsch: I have, over several years, Tested EVERY Major History Manager for Chromium Browsers, And, by a Wide Margin, “History Trends Unlimited” is the Very BEST!! A few of the others had This Or That Special Feature, But H.T.U. is the Rolls Royce among them all. Along the way, I ran into a minor niggling question & contacted this Extension’s Author, Mr. Lauen, who graciously answered my concern with impressive speed.
• (2023-10-17) Gustavo A: To make it work after the migration I had to remove the extension from Chrome, close chrome, re open chrome after a couple minutes (just in case), re install the extension and import the backup file. After that is working perfect with my 5 years of history.
• (2023-10-14) Tami Toivanen: Very useful add-on which would be 5-star worthy with ease as Google itself has opted to not provide browsing history locally for longer than ~90 days, but as of late (September 2023 -> onwards) it has become unreliable at keeping the history accessible due to recent changes on Chrome which causes losing all history due to database corruption(s). Here's hoping that the issue can be fixed, as the extension has been very reliable and powerful tool during my 4 years of use before these recent issues.
• (2023-10-10) 小号: it's very useful extension，if can translate to Chinese language will be nice, please consider my request。
• (2023-10-09) vicentory: History Trends Unlimited uses a storage system (Web SQL) that will soon be removed by Chrome (details can be found here). Your data must be migrated to a new storage system (SQLite WASM). The migration is simple: just follow the steps below. You must migrate to continue using this extension. If you don't migrate, your data will eventually be deleted by Chrome! please fix it,it's very useful extension.
• (2023-10-06) Robert Brown: A little over two years ago, I discovered that one's web browsing history on Chrome has a three-month limit. Since then, I've been using this extension to keep a permanent, searchable record of my browsing history. I've transferred this data between computers and restored from backups when I've had problems. For my purposes, this extension is functional and reliable. I wish I could include my mobile browsing history somehow, but that lack is no fault of this extension. Many thanks to the developer for creating and maintaining this tool – and offering it for free! I highly recommend it.
• (2023-10-05) Nicholas Escalona: after using for a long time, began receiving "database is locked" or "database disk image is malformed" errors. have weekly full backups, so following faq, reinstalled extension. on both of two most recent backups, receive "Imported 0 urls and 0 visits", "Errors: 39,109 lines could not be imported". wasted my time.
• (2023-10-05) Patrick Labay: Love it, although I do wish you can change the file name format for the auto backup because I use multiple profiles and the auto backups could get mixed up since they have the same file name format
• (2023-10-03) Eli Luong: Great extension to capture history and present it in useful data visualizations. Awesome developer!
• (2023-10-01) River Burnell wojtech: good (:
• (2023-09-29) Kasper: After reinstalling the extension and importing my backup tsv 9 days ago, I'm getting this error again: "SQLITE_CONSTRAINT_PRIMARYKEY: sqlite3 result code 1555: constraint failed" error message
• (2023-09-23) achraf mirrane: Great extension, and for anyone that has the sqlite3 result code 11 error after the last update, try removing and re installing the extension.
• (2023-09-23) Ayan Agrawal: Was a nice extension but it doesn't work anymore, gives the error SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed
• (2023-09-17) Александр Марков: not working after database migrating SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed or SQLITE_CONSTRAINT_PRIMARYKEY: sqlite3 result code 1555: constraint failed
• (2023-09-17) Andrea Panada: An important message for both the creator and the users: since the recent change in data storage, *it appears* that using programs such as CCleaner to clear Chrome web cache deletes the saved history. I am not 100% sure if it was really what happened, but anyway, be careful. Not sure if there is a way to prevent this. In the meantime, backup before clearing the cache.
• (2023-09-16) Yeran DBU: Hey, I've been using this extension since 2021 and it's great. However shortly after the latest update hit I started to get this Error message: "Error message: SQLITE_CONSTRAINT_PRIMARYKEY: sqlite3 result code 1555: constraint failed" Any help would be appreciated.
• (2023-09-15) kuba4ful: unsure where to send a ticket, there is no github repo or something so i'll write here after the focred migration the extension broke. can't search for anything, it says "sqlite error 5 'database is locked' " i love this extension, so i'll gladly change the review to 5* once this breaking bug is fixed
• (2023-09-14) Björn Zosel: awesome tool!
• (2023-09-12) •Sm0k3•: Great extension
• (2023-09-12) Reinis Zumbergs: Have been using it for many months now. It does the job great. Chrome is going to change some underlying technology, so the authors of this extension provided migration ahead of time. Hats off to them for caring for the users.
• (2023-09-11) AA_27: Should i migrate to SQLite WASM if i'm on Windows 7 since Chrome is not updating anymore?
• (2023-09-10) Markus Krainz: Exceptionally useful and well maintained extension.
• (2023-08-27) TV DFM ZPRÁVY: After chrome crashed I had to re install this, because the history was deleted from the extension, but not from chrome itself.
• (2023-07-21) GamingPro: Nothing to show you how to even use this!
• (2023-07-14) Harsh Singh: Great Extension!! Working as intended. But It should have an option to exclude certain websites from saving in history. That's a must. If it gets added, I'll rate the extension to 5 stars.
• (2023-05-18) Sandeep Singh: Been using this for about 3 years now, this thing is just incredible. I love being able to search my history, for an unlimited time back instead of just 3 months, which is so stupid! So much usefull links I've been able to find again, which I never would have otherwise. The trends tab is cool, fun to see what kind of sites you visit. The backups are super usefull, so I'll never lose my history. Should be standard in any browser! I installed it in my other chromium based browsers too. Thank you for creating this!
• (2023-04-24) Zack Light: It should have the option to save to GitHub in the background Having to deal select the corresponding folder for the history file is too much work, each time I restart Chrome. Check out the extension LeetHub which syncs in the background.
• (2023-04-17) Florian “furomin” Gaul: Very neat tool, sadly it's not on github or even open source... 😥🥸
• (2023-04-14) Richard L: Just great. Easily one of my top three extensions. I find history invaluable in many ways, including problem-solving, and this extension expands Chrome's paltry 90 day limit to UNLIMITED! And it further provides options such as auto history backups in case anything ever goes awry (which has never happened to me in years of using HTU), and a function for transferring the info to a new device. I have to remember that when I *do* prefer to delete certain history items less than 90 days old, it's necessary to separately delete them from Chrome's history as well, since HTU wisely keeps its own history files completely separate from Chrome. Thanks so much for this extension!
• (2023-04-11) Jonathan Vargas: It's great but it would be useful to implement a "time per site" option, not only visit.
• (2023-04-08) Liam: 7/4/2023: the extension' data suddenly become empty and i can't export and import history, what the hell OLD: All of my 2 years or more of data was lost after I re-enable the extension! Are there any ways to recover it if I didn't export history? And why did that happen Reply 1: That is the only time the data was lost after I re-enable the extension, the other times are fine. I'm using Chrome version 96.0.4664.93. This loss hit me so hard OMG. Definitely will use Auto Backup from now on... Is it possible to make the extension be albe to read and import history from Google My Activity?
• (2023-03-22) Petrus Rademeyer: Great addon and works 100%. Especially for those days where you just cannot remember what you did the last couple of days and got in trouble to due work load :) Cheers
• (2023-02-28) 马春杰: Thanks, plugin is very good, can you add gist synchronization?
• (2023-02-21) 刘志东（小小东叔叔）: 不错，可以很好的整理历史记录
• (2023-02-18) Shion Sinx: One time I needed to check some website I visited many months prior, and found out Chrome limit of 90 days of browsing history. I looked and asked around and was pointed to this extension, it seemed very promising! Installed and forgot about it. Until today when I needed it, so I went back to check a website I visited about 4 months prior... and found nothing. There was no records older than 90 days, again. Only then I learned that the sole funcion of the extension is most likely tied to this option of auto-backup which is NOT turned on by default! And no warning about it as well (because if there was I would have turned it on). Why would someone do that?!

Latest issues

• (2023-11-28, v:1.7.4) David U: Stopped working. History only shows a few items and only for 1 day.
  About a month ago History Trends in Chrome stopped working. It does not save all my history. Also, last week, I imported all my history from 2 years ago, then, the following day, it was no longer there (in history trends). So, the plugin no longer stores newly generated history, and it no longer stores history for more than a few hours.
• (2023-11-19, v:1.7.4) Jeric Jan Cantil: Auto backup doesn't work?
  It's enabled. I got set it to "Full" at an interval of 7 days. The last backup was on 11/4/2023. Since then, no other backups have been made.
• (2023-11-04, v:1.7.3) Jeric Jan Cantil: Lost all history from Oct. 19, 2020 to Oct. 12, 2023
  This is more of a notice than a problem. It must have been the migration. I had a full backup file made on Oct. 19, 2020, but that's all. Very unfortunate. It might have asked me to do a backup before migrating? I don't remember. I can't really blame you. It's on me for not backing up. It is what it is.
• (2023-10-29, v:1.7.3) Andrei Iosifescu: no such vfs: opfs
  When trying to migrate, the error message "no such vfs: opfs" is displayed on the page. Also, I am using Edge, I don't know if the changes Chrome made will affect Edge.
• (2023-10-27, v:1.7.3) woz: Unrecognized return value from import-worker
  I have a backup file, but it's not being imported, and I'm getting an 'Unrecognized return value from import-worker' message.
• (2023-10-23, v:1.7.3) Tomáš Kolinger: Database issues
  I have persistent issue with SQLITE_CORRUPT, it happened 3 times already. HTU works for a while then I get corruption again. Multiple Chrome versions, currently Google Chrome 118. I have backup but import process is slow and settings need to be setup again - not nice to do it over and over again. Is there any workaround or anything I can do about it? I also noticed that overall speed dropped by a lot. I have many visits (2.5M) so I don't expect speed but 1.6.2 is many times faster with identical dataset - every operation feels slower and Import/Export or Trends is very slow in comparison (10s vs 50s+). Is this another side-effect of the new SQLite database? Feels wrong that Google forces developers to use technology that doesn't seem to be ready yet.
• (2023-10-20, v:1.7.3) Tab Let: Multiple browsers
  Are there any issues if using multiple Chromium browsers e.g. Chrome and Brave with regards to the incremental save location confusing the backups?
• (2023-10-16, v:1.7.3) Carsten Svendsen: Does not save history for more than a day after the migration
  As the title says, and it makes this entire program or extension useless. I have 3 years of history saved in a backup files, but now I can't continue to do so. I'm using MS Edge on W11 by the way, but it runs on chromium so that should not be the reason for this. I see other users with the same problem as well.
• (2023-10-12, v:1.7.3) Tami Toivanen: Frequently corrupting database
  Ever since the migration of databases, I've been getting "SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed" every time after restarting computer, at latest today afternoon. This is fourth time on my main workstation since the migration requirement, so in few weeks for now. When I manually close and start Chrome, there aren't any issues as supposed at minimum but when I click restart from Windows while Chrome is running, database seems to get corrupted with very high probability. I don't use the option to force close programs when Windows gives the list of programs waiting to close before restarting so I can only assume that Chrome and all addons should close gracefully. Anyways, as these issues never happened before the change from WebSQL, could you as the developer provide the oldest version before the extension was updated away from it? I'd rather use it until at some point it literally would stop functioning.
• (2023-10-11, v:1.7.3) emrah yalcin: Error message: SQLITE_BUSY
  The extension doens't show anything and it gives this : "Something went wrong with the search. Please see "Search Tips" for a list of valid search operators. Error message: SQLITE_BUSY: sqlite3 result code 5: database is locked"
• (2023-10-10, v:1.7.3) Alber AXE: History dissapeared again and again...
  This version definitely does not work at the moment... I don't know if it's the automatic Chrome/Brave updates or what, but every week I manually check the history and I see that it only shows me the last day or the last 2 days. So there is some point when the entire history is broken and reset. I cannot explain but it failed every week of last 7 weeks.
• (2023-10-09, v:1.7.3) mindlord phir: Feature request
  1)Export folder other than Downloads 2)Import all incremental backups at once 3)Google Takeout JSON formatter be a part of the extension instead of jq
• (2023-10-07, v:1.7.2) Rolf van Vliet: I have to manually save backup file?
  Since two weeks or so, HTU asks me to save the backup file when chrome starts (so it happened twice, I think). At first I had no idea what this random download file was as I've had this extension for a long time. It asked me to save htu_autobackup_20231007_incremental.tsv and with google I found that htu was this extension. Isn't this supposed to happen without my intervention? Or is this normal behaviour and is it just the first time it's worked? :P
• (2023-10-04, v:1.7.2) James Wright: All history lost after backup a few weeks ago
  Something went wrong with the search. Please see "Search Tips" for a list of valid search operators. Error message: SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed Please help.
• (2023-10-04, v:1.7.2) Jonathan L: Unable to view history or export
  An error occurred: SQLITE_ERROR: sqlite3 result code 1: no such vfs: opfs
• (2023-10-02, v:1.7.2) Kelly Hunt: Database export problem
  After upgrading, followed the steps to backup and then let the converter run. After it was finished, tried a search and received "SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed". Tried to import the backed up TSV and after an hour it was finished (took longer than the initial conversion). Tried searching again and same issue. Uninstalled/Reinstalled extension then imported from the backup TSV. After processing, it still gives the same error. Then took a look at the TSV and its missing the last 2.5 months of history. In my case, the TSV is almost 1M records. My guess is possibly the TSV is corrupt or the importer is having issues parsing. Also appears that after doing the conversion the WebSQL db is gone from the user profile so unable to create a new backup.
• (2023-09-28, v:1.7.1) Alber AXE: History dissapeared from yesterday
  I have the 1.7.1 extension on 2 computers. The current Brave/Chrome versions on them are: 117.0.5938.92 (64 bits) 117.0.5938.132 (64 bits) Suddenly, I have checked the history and I have only data for the current day in both computers. Of course, I did not deleted manually. What happened? Could I restore from weekly auto-backup? Where is the auto-backup file? I found at FAQ that "Because Chrome is deprecating and removing Web SQL, the history database is no longer stored as an independent file on your file system. Instead, it is now contained within binary files maintained by Chrome (aka, the OPFS) within your Chrome profile directory." What can I do? Many thanks in advance.
• (2023-09-24, v:1.7.1) Hunter Scales: date format in exported history
  In the .tsv export file, the second column appears to be a date. Can you tell me the format of this date field and how to convert it to day/month/year etc.? Thanks.
• (2023-09-20, v:1.7.1) Çağatay Ustaalioğlu: Custom Backup Folder
  Will you integrate File System Access API so that we can select custom directory for backups? Any way for us to backup to a different folder is really appreciated.
• (2023-09-16, v:1.7.1) Markus Krainz: Database broken after last update
  Unfortunately after the conversion of this extremely helpful extension I get: "SQLITE_CONSTRAINT_PRIMARYKEY: sqlite3 result code 1555: constraint failed". Can I provide any data to help fix this?

• (2023-09-16, v:1.7.1) adac7786: recent update broke my history
  every since the recent update it is impossible to see more than the previous 3 months of my chrome history. ive tried reinstalling, using the backup iw as prompted to make before the update and using a manual update from about a month ago that i made myself. ive been using this extension for years and losing all my data would be a huge loss.

• (2023-09-12, v:1.7.0) Tommi Immonen: Migration failed
  Hi! I went through the migration process the app prompted me to do and at the and it promted that the migration was succesfully done. However when I tried to use the app afterwards i only got this error message: "An error occurred: SQLITE_CORRUPT: sqlite3 result code 11: database disk image is malformed" and it seems to me that my history is lost???
• (2023-09-02, v:1.6.2) Michael Rienstra: Search: increment the date ±1
  When the search query includes a date, e.g. `date:2023-08-24`, it would be really nice to add controls to increment the date ±1, to easily allow moving forward or back a day without having to manually change the date each time.
• (2023-09-02, v:1.6.2) Michael Rienstra: Open source? Bump dependencies.
  Great extension! I see you're working on a new version to deal with the Web SQL deprecation. Wondering if it would make sense to make this extension open source, so your developer users could potentially help with that and related efforts. E.g. I noticed there are a number of older dependencies, the most extreme being DataTables 1.9.4, which was released in 2012: https://datatables.net/forums/discussion/11894 Granted, "if it ain't broke"... Anyway, just a thought! Thank you and keep up the good work!
• (2023-07-31, v:1.6.2) gyakkun: Demise of WebSQL API in Chromium 123
  Hi Randy, as you may notice that the Web SQL functionality would be removed permanently since Chromium 123 (https://developer.chrome.com/blog/deprecating-web-sql). May I know if there's any plan to switch to WASM version of sqlite for this extension? Thank you.
• (2023-07-20, v:1.6.2) mindlord phir: Some visits are missing
  My search history in the extension for yesterday only has 35 entries most of them are "youtube.com" even though I watched different videos, not just refreshed home page. My browser search history has 308 entries from various sites.
• (2023-06-11, v:1.6.2) John Adamidis: exclude the same URL from appearing in the search results
  Hello! This is a brilliant extension and thank you for sharing it with us. I’m trying to find a way to exclude the same URL from appearing in the search results, however, without success. In the options, there is this choice: “Sync History: Ignore subsequent visits to the same URL when they occur within 86400.0 seconds of each other. (This helps reduce large spikes in visits on some websites. Set to 0 to disable.)” As you see I set the interval for one day, however, even when I refresh the page, it shows again in the search results, even 5 visits in a few seconds. (if I continuously refresh to check it out) I guess I’m doing something wrong. Can someone help me to solve this? Thanks!
• (2023-06-02, v:1.6.2) John Adamidis: duplicates in history
  It's a great extension and I’m happy to have found it. Is there a way to find duplicate entries in history and delete them? It happens very often that I’m visiting the same webpage and seeing it multiple times in my history is a bit awkward. Thank you!
• (2023-05-29, v:1.6.2) Zach Poblete: How to transfer native browser history to History Trends Unlimited?
  I think I lost my History Trends history due to a browser crash, but my latest backup is from two months ago. Is there a way to append the native browser history to that backup so that I can continue like nothing happened? I am using Microsoft Edge, but maybe the way to do it would be similar to in Chrome, if it is possible in Chrome.
• (2023-05-08, v:1.6.2) Neil F: Searching by URL
  Firstly, thank you for this invaluable extension! It's common for page titles to be inaccurate and not descriptive, e.g. "Product Item" for all products on the site. It would be supremely helpful if the searching would search the URL as well, not just the page title.
• (2023-04-04, v:1.6.2) Pantelis Emmanouilidis: sometimes the extension doesnt sych corectly
  I cam into that problem: sometimes, when I go through webpages, and after that, I open the extension (to synch automatically), I see my history visits, but some of them isnt displayed, but on chrome (my browser) they displayed correctly. I found that bug some weeks ago, and I have the extension more than an year.

• (2023-02-14, v:1.6.2) Rick Williams: Wildcards or substring matching for trend filters?
  Being able to filter by all URLS containing "keyword" would be very useful. Examples: - All URLs beginning with github.com/username + don't have to type the protocol + can filter by something between a whole domain and single URL - URLs containing "topic" + If I read about something across many different domains One step further would be to allow multiple URL filters and multiple Domain filters, with the Boolean logic being: (domain1 OR domain2 OR domain3) AND (URL1 OR URL2 OR URL3) But honestly just the substring matching would be excellent.
• (2022-12-03, v:1.6.2) ZaCloud StriFair: Suggestion for potential ways to fix the inability to auto-backup when users have Chrome set to ask for download location every time?
  Yo, dude. :) I see by a recent reply in the reviews that you might be considering fixing that shortcoming I mentioned before after all, due to Chrome's "ask where to save download" window thing (which I & many other users need to have turned on). I made a couple suggestions in my July comment on this Contact page, as well as the reply to myself with an additional musing. I'm not a programmer, but just figured I'd suggest a few potential workarounds based on things other extensions are able to do, in case something sort-of-similar can be attempted. Just letting you know in case you missed those. (Probably useless but oh well, figured it's worth a try anywaaaayyyy.... ^_^;;)

  Hi Randy! Epic plugin! I have this issue where it seems the plugin never starts, the search page is stuck on "Initializing..." — any idea what could be happening?

  I cannot find the button "add to chrome" in my tablet chrome web store. Is it normal? Thank you for your kind answer.
• (2022-08-05, v:1.6.2) FInx Rake: Would love an option to prevent title changing when re-visit the pages
  While I like this extension for keeping the history of URL I visited in the past, re-visit some pages again that have their site's name or title changed, like Youtube title video for example, will affect the past history. Other user has mentioned about this too, but I'm hoping there will be an option to prevent the title changing for same URL page, to keep it in history. Or choose to have it change in case some users don't want the history data becomes bigger or something
• (2022-03-17, v:1.6.1) Joseph Myers: Why is my history missing?
  Any reason why some older history (e.g. January 13th) would be missing? Some days only have a single entry, which is suspicious, because I can't do anything productive with a single website request. January 2-5 have no entries at all. For example, I know for a fact I watched the CFP National Championship, January 10th, on my laptop -- but there are only four entries that day, all google sites. Another example, my personal favorite, is the 15th, where it says the only time I used the internet was to do a single Google search for "wildebeest" :D What am I not understanding? Why would only some of my entries in a day be missing?
• (2022-03-09, v:1.6.1) Martin Zackery: Searching the database using keywords.
  In the advanced search option, I input several keywords and separate them by commas however no result is returned even though I know the keywords I used are definitely associated with several other search results, which has led me to the conclusion that the keyword search only performs the search on links that have all the keywords mentioned, and not on any link that has at least one of the keywords selected, is this correct? If not, how do I perform a keyword search that produces multiple search results that have any of the keywords I selected, in the links?
• (2022-01-05, v:1.6.1) Travers 15: How do I import the locally saved history from the Chrome browser to the Opera browser?
  The History Trends Unlimited extension is successfully installed in my Opera browser and I thought if I just copied the entire database that is stored in the "chrome-extension_pnmchffiealhkdloeffcdnbgdnedheme_0" folder, which is in the Chrome profile directory, and pasted it into the folder where the History Trends Unlimited database is stored in the Opera profile directory, (which is file path: C:\Users\<USER NAME>\AppData\Roaming\Opera Software\Opera GX Stable\databases\chrome-extension_pnmchffiealhkdloeffcdnbgdnedheme_0) then all of the history that was saved while I was using Chrome would be imported into Opera. However, it did not work. Also, I removed the two files that were in Opera HTU database folder before pasting the database I copied from the Chrome profile directory. Is it possible to import the Chrome database for HTU into the Opera browser?
• (2022-01-03, v:1.6.1) A Raccoon: Re-visiting a page that is now deleted will distort history
  If I visited a YouTube video 2 years ago, I can find it in History Trends and revisit that page. If YouTube removed that video, it gets a new page title. If I search for it in History Trends again, it has now vanished. The title is missing, as if I had never successfully visited that video. This distorts history and frustrates my efforts to track things down.
• (2021-12-30, v:1.6) A Raccoon: Will this extension work in any other browser?
  There are a number of Chrome-based "privacy browsers" on the market today and I am wondering if it's possible to transfer this extension over to one of those browsers. Your extension is one of the few things holding me back. Are you aware of it being used in other browsers, and if so, do you have any instructions for migrating?
• (2021-12-17, v:1.6) Lazar Ranisavljevic: Search not working
  Hello, Like one more person that is using Vivaldi, search is not working for me, and for a long time now, several versions of Vivaldi. After a search is performed it returns the message: "Something went wrong with the search. Please see "Search Tips" for a list of valid search operators. Error message: could not prepare statement (1 no such module: fts3)" Is there a workaround or does it just not work with Vivaldi and that's it?

• (2021-08-07, v:1.6) A: Join old browsing history files
  To reunify old histories before installing this extension, I suggest to add a way to import from old chrome files or from texts extracted with ChromeHistoryView program ( https://www.nirsoft.net/utils/chrome_history_view.html )
• (2021-07-29, v:1.6) Ant 1597: Error (no such table: search_urls) in Vivaldi browser
  I am using Vivaldi 64-bit since about 4.0.1 to now, ver. 4.0.2312.41 on Windows 10 (Chrome ver. 91.0.4472.166, V8 ver. 9.1.269.39). And every time I use the search function, I get the following error message: > Something went wrong with the search. Please see "Search Tips" for a list of valid search operators. > Error message: could not prepare statement (1 no such table: search_urls) (No more error message in WebDev console, by the way.) It will be really nice if this problem can be fixed. But still, it is absolutely not the extension's problem, very likely some core function incompatability. (The function works fine on my Google Chrome browser.)
