• (2023-10-03) status102: 挺有用的，但是在标签页较多时容易造成Chrome崩溃，而且比较卡顿、消耗CPU资源较多。 在500+标签页时，有时会出现标签页数量统计出错
• (2023-08-03) Victor Cretu: This extension is really a life saver for people that open tens of tabs. At that point you start to loose track of open tabs and duplication starts to happen. This extension has saved me from duplicating my work inside the browser.
• (2023-05-10) Cobus Van Wyk: My work requires loads of research and I've had the Clutter Free extention installed on all five my browsers for years and its magic. I regularly have 30 to 120 tabs open on each of the 2 or 3 browsers that I use simultaneously, and to date CF unerringly prevented any tab duplication, which helps massively in such an overcrowded desktop environment.
• (2023-03-16) Syed Ashraful Karim: Works fine. But I think it should refresh the already open tab when the new duplicate tab is not opened, or there should be a settings whether I like to refresh the opened duplicate tab which is gonna highlighted.
• (2023-03-05) Ym M: I was using this with hundreds of tabs open and was working flawlessly. However, something changed recently that made chrome extremely slow opening a new tab when this ext is enabled. Only option was to uninstall it.
• (2023-02-21) Adam Clark: About a week ago, there started to be an appreciable pause when a new tab is opened and chrome freezes for a few seconds. I went through and disabled all extensions and it was only until this one was re-instated that the issue returned. Even does it when just typing into the address bar sometimes, I guess it is triggering the Url change hook or whatever it uses to de-dupe tabs.
• (2023-02-21) Roderick Dunn: Works well until you have a certain number of tabs open, then chrome starts moving extremely slowly. I had to disable it for now because I always have a ton of tabs open. Would recommend for people who don't keep 50+ tabs open.
• (2023-01-27) Konstantin K.: It was fine extension when it closed duplicate tabs automatically. Unfortunately now in settings this option is marked "Hard limit—Block new tabs when limit is reached. (not yet ready)".
• (2022-12-17) Cristofer: asco de extension,usa demasiada cpu en veces y aveces ni siquiera marca las pestañas duplicadas
• (2022-12-16) Cade Michaels: Great tool. Really needs ability to disable temporarily though. Sometimes I want to open something in multiple windows but I either have to remove the plugin completely or add rules. Right click menu or in plugin context menu would be great.
• (2022-12-16) Nathan: Floating window refuses to work no matter what which cripples the app.
• (2022-12-16) s tory: Recently this extension no longer works with my opera developer browser.74.0.3904.0 Windows 10 64-bit.
• (2022-12-09) N. Somniak: Used to be a great extension. Over the last month or so, however, its behavior has become erratic and inconsistent. It only actively closes duplicates sometimes, and it is unclear what logic it is using to decide when to act or not. For example: I just duplicated a window of 10 identical tabs -- the extension identified and closed one of them, but left the others open. When opening the extension sidebar, I can see that it recognizes the other 9 tabs as duplicates, but isn't doing anything about them. And yes, I confirmed that the extension is running in "active" mode, as evidenced by the ONE duplicate it did automatically close. And this is not an issue of some timestamp or other weird string being in the page URLs, because as I noted, the sidebar IS identifying them as dups. I used to love this extension. I want to love it again, so I hope this is sorted out soon.
• (2022-12-02) Ged Oni: Freezing with a lot of tabs. "Prevent duplicate tabs" works ok in such cases
• (2022-10-28) Aleksandar Penev (aleksoft): After chrome update stop working and start show this error page: Your file couldn’t be accessedIt may have been moved, edited, or deleted. ERR_FILE_NOT_FOUND
• (2022-10-27) Fabio Rufino Gallo: It was great until recently. I have a lot of tabs and now every time I try to open a new one, Chrome freezes for a few seconds (anywhere from 5 to 15). Also, sometimes it freezes while writing emails in the web Gmail interface, editing a field in a form, or even typing an address in the address bar!
• (2022-10-25) Kok-Liang Lim: Was great, since last update it lags chrome so much, open/close/switch tab lags, if you have alot of tabs, it freezes whole chrome completely
• (2022-10-24) uğur deniz kılıç: Was great. But now, it started to freeze chrome.
• (2022-10-20) Tim Kwist: As someone who frequently has 3+ mail tabs, plus endless copies of other random knowledge base docs open constantly, this extension has been the game changer that I wish I had found years ago!
• (2022-09-17) Александр Шлычков: Все бы хорошо, но как и все опробованные расширения такого типа, работает через раз. Может быть, конфликт с Auto Tab Discard.
• (2022-08-14) didier Namur: Je l'ai installé pour gérer les onglets dupliqués, ça n'a pas marché. En plus quand je l'ouvre, en passant la souris sur les titres des onglets, ça les met en 1er plan, du coup, si ce sont des onglets youtube, ça lance la vidéo de la page ! Si on passe sur un autre titre, ça lance une autre vidéo et ainsi de suite ! Je ne sais pas si c'est l'extension qui est ainsi ou si c'est une autre extension qui lui donne se comportement, mais c'est insupportable.
• (2022-06-29) Roman Dabal: Easy to use, gets the job done.
• (2022-06-28) Дмитрий Голик: Жрёт процессор, тормозит, глючит так, что приходится браузер перезапускать.
• (2022-06-06) Richard Barrott: Works well. Stops me from having too many copies of the same tab open. Thank you!
• (2022-06-03) Dwayne Kuan: Poor performance. Took 15 secs between clicking its icon In chrome and for a window to pop upI this is due to the number of tabs I usually have open. I had 185. don't use if your super producitivity sort of person with many tabs open.
• (2022-04-30) Lorin Halpert: Worked for years, now no longer closes duplicate tabs
• (2022-01-19) Matt B: This extension does what three or four extensions combined does. It is detailed and includes tweaks that I would say "I wish I had it". I have not found any bug or any issue so far. I am a supporter for the extension and would love more people to support the project.
• (2022-01-18) Person 1: It's very good. Does what it's supposed to but sometimes you can't open a new tab because a new tab page is already opened in another window. Please fix this bug. It also happens in Edge browser.
• (2021-12-04) Rob K: THIS EXTENSION HAS ADVERTISEMENTS. I received a desktop notification from google chrome, generated by this extension, telling me to download "AutoConvert Select" have had this extension for a few weeks, was recommended by a friend. deleted it as soon as i got that notification. (no option to disable ads in the settings)
• (2021-11-19) Liz Panton: This was working fine then today it was disabled automatically with a message that it required a new permission to know my email address. Why does it need to know my email address? Then there was a popup also saying it needed permission to "read and change all your data on all websites". What???
• (2021-11-18) Martin Pool: It popped up a spammy notification to install a different extension from the same author, which seems like a breach of trust... Too bad because it seems like a good idea, although I'm not sure it was completely working.
• (2021-07-10) Alessandro Saeli: Very effective!
• (2021-07-06) Justin Akers: This plugin works like a dream. I declared tab bankruptcy at >350 open tabs recently. Installed this laptop and I'm hovering around 60 by avoiding duplicate quip and gdocs tabs etc. Thanks!
• (2021-07-06) Rus Schmidt: Super-useful extension - I really couldn't do without it. The help popups in the settings menu are very clearly written, although the extension works fine with the default settings.
• (2021-06-03) Ethan Smith: Get this! If only for the ability to search open tabs with ctrl+shift+f
• (2021-05-31) Ifer30: Having a lot of errors. Can't open options page, hangs forever. Not closing duplicates and can't see the list of them. Number on extension icon slowly rises, does not match number of tabs visible on another extension icon.
• (2021-04-28) Andrew Xia: Absolutely phenomenal. However, now that The Great Suspender is banned, it lost some of it functionality. Hopefully it works with the built in suspension on Edge. Other than that, it has saved me so much time. It still works well with over 100 tabs
• (2021-04-23) Pedro Petroli: The tool is great! It would be awesome to have for recognise tabs on unfolded grouped tab.
• (2021-04-18) Andreas: Great extension but doesn't work in incognito mode. If that gets fixed it's 5 stars for sure.
• (2021-04-04) Sandra power: I AM GLAD THAT SOMEBODY CAN KEEP THE BALL SOMETIMES WHEN I AM NOT THAT SAVVY WITH THE WHOLE PICTURE, LATE USER,BABY BOOMER WITH MOST BUSY BUT PHYSICAL DEMAND WHEN I WORKED ,THAMKS FOR THINKING ON YOUR FEET. TEE HEE,HAPPY EASTER SANDI P.
• (2021-03-10) Petr Matlas: It worked quite well in cost of little bit extensive CPU and memory load when I end up with so many windows and tabs. I have the chrome startup option sets to "Continue where you left off" (last session) and I never had problem with this. But a few days ago this extension starts totally hang up Chrome during startup (with many tabs and windows from last session otherwise it starts normally) so the Chrome never runs to usable state. On browser start-up all browser windows from last session starts open one by one with some cached content, but within a while it starts opening just empty windows. GUI of all browser windows is frozen since then and many windows are just totally white, others has tabs, toolbar and address bar but the canvas of the window is empty, just background color of the theme and only a few of windows has partially loaded content in active tab. Chrome extensively load CPU and main Chrome process eats around 6 GiB RAM, but it is not reacting to any user input (except if I click on other than active tab, the text on corresponded tile on taskbar is changed according to tab name, but it does nothing in browser window itself) and there are no open sockets in the main Chrome process. I have no other option than to kill Chrome then. When I remove the session files, start Chrome up, turn the extension off, exit Chrome, return the session files back and start Chrome, then Chrome starts up normally and works fine. But if I then turn the extension on, Chrome totally freeze. So I have to kill Chrome. I found out, that if I starts Chrome after that again it starts up normally but the extension is off - so Chrome hung up so fast that it even didn't write change, the turning on of the extension, to the configuration file. I tried to remove the extension and install it again from the Google Store, but the result is the same.
• (2021-03-04) Akos Korosmezey: Great extension, I like it very much! One suggestion: I use a lot of tabs and it would be more convenient to use an optional compact format of the tab search window.
• (2021-02-07) allmighty Asian: Settings options isn't available in kiwi browser there's a blank page only
• (2021-01-26) F_ck Off: This app is doing more harm than good. Because when you open a copy of a tab, it is removed from the group. And you need to drag it to the group every time over and over and over again.
• (2021-01-16) Javier F: Absolutely useful. An option to hide the context menu please.
• (2020-10-14) 兰凌潇: 很有用，希望在打开重复页面时能自动刷新，页面内容往往已经过期了
• (2020-09-16) Ed Castano: This is a most have Chrome Extension and an essential part of my workflow.
• (2020-07-28) Michael Koren: I click on "Show list with duplicate tabs" and nothing happens, no loading screen, no new window. nothing. Version 8.22.14 When a window does open, its after 5 minutes, its super slow. the list keeps updating so when I decide to click something it just brings me out of focus an back to the top of the list all the time. its very frustrating. you can not do multiple, but, SPECIFIC selects, you have to manually click one [X] at a time. you can either close all tabs or close one tab, not specific multiple tabs all together just one at a time, its very slow. Every time you click on [X] the page takes about half a minute to refresh again during which no clicks work. Clicking on scroll sometimes does nothing when the window is stuck. I believe you should not force the window update rate to be so high all the time, prevent focus loss (middle or bottom scroll becoming top scroll) and basically detach the ui from the real time situation so that the user can take their time and launch a few commands that will take place async without effecting the user experience. My main problem with this extension is that while its loading after enabling it, it completely blocks regular chrome from working till it finishes loading. I can not use chrome at all till it finishes. Couldn't you make it's loading process be less blocking? This was made to fight slowness, not cause it :( Also - close all dup tabs could be super dangerous in making important work disappear, you should add a "are you sure you want to delete X dup tabs?" what if the user mis clicked it by accident? tons of lost work disappeared unwillingly. Make sure "OnFocus" to the extension window does not trigger any GUI button clicks, just brings the focus and that's it. a second click after focus achieved should actually trigger things, since this is dangerous! and unlike chrome's built-in undo close tab CTRL+SHIFT+T, in here there is no undo and no "are you sure you want to?" just a quick closing and your work disappears. The one good thing about this extension is that I feel safe about and I like is "search for tab by name"
• (2020-03-05) Lukas Folmert: Closing duplicated tab and focusing on original tab doesn't work correctly when those 2 tabs are in different windows!
• (2020-01-24) Jefferson Ogata: Used to work. No longer does in Chrome 79 on Linux as of 2020-01-25, possibly earlier. Fails to identify any duplicates.

• (2017-03-03, v:2016.1114.2.14 release) Karol Depka Pradzinski: Bug - switching to a certain tab every few seconds
  Hi. At some point the extension starts to stubbornly switch to a certain other tab every ~3 seconds. How to fix this? Thanks for your good work.
• (2017-02-15, v:2016.1114.2.14 release) Alison Sonnenschein: Viewing Duplicate Tabs
  Hi, I was wondering if there's a way for me to see a list of sorts of all the duplicate tabs (or visual queue that helps user identify duplicate). I'm hesitant to delete all duplicates before actually reviewing what they are/what's being deleted. If you could let me know if there's a way to see a duplicate tab before deleting all duplicates, that would be a huge help. Thanks!
• (2017-01-12, v:2016.1114.2.14 release) Stephen Goult: Stay on source tab not working correctly
  Hi, When I selected option 3 under duplicate link behaviour, I expected the foreground tab to remain open while the background duplicate would be automatically closed instead the foreground tab is closed as if option 2 were selected. Is this the intended behaviour? Thanks
• (2017-01-02, v:2016.1114.2.14 release) Mohammad Mahdi: Not working properly in Vivaldi Browser
  Hi Thanks for the Extension but I can't Whitelist the empty tabs (speed dial page) in Vivaldi browser which I think is related to the fact that each and every tab in Vivaldi is named by a hash and not simply a name... could you please modify the extension so that it would work on Vivaldi (of course that extension works everywhere else in Vivaldi but you can't have multiple empty tabs open)
• (2016-11-25, v:2016.1114.2.14 release) First name Last name: Statistics Notification & Duplicate Tab Shortcut
  Could we get an option to disable the notification that tells how well the extension is performing? I love that the extension is working and I'm happy with how well it works, but it's becoming a bit tedious to dismiss the notification every time I log in. P.S. a "duplicate tab" keyboard shortcut would be really convenient and appreciated. Thank you!
• (2016-11-18, v:2016.1114.2.14 release) Max W.: occasionally preventing page loads
  Hello Aditya, I think I've found another minor problem and it dawned on me that reviews aren't a good avenue for feedback. Since the recent update, on my system (Chrome 54.0.2840.87 64-bit on OS X 10.11.6) it sometimes prevents pages from loading. It doesn't matter whether I open a new tab and enter a URL, or CMD-click a link: in about 5% of cases, the tab will not do anything. CMD+L > Enter or CMD+R usually causes it to load properly, although it sometimes happens twice in a row. Disabling the plugin removed the issue. Best, Max
• (2016-10-03, v:2.4.4.1 release) doesn't work for all URI's
  Doesn't detect trailing "/" and other URI prams.
• (2016-08-29, v:2.4.4.1 release) Jacob: Doesn't detect intranet links as same as internet links
  Say you're running an internal tool, lets say jira. You can access it via jira/browse/xyz. If I get a link to the internet url like, jira.company.com/browse/xyz the tool thinks they are different.
• (2016-07-05, v:2.3.0.0 release) Iv She: ver 2.3.0.0

• (2016-05-20, v:2.0.0.5 release) dragon788 (dragon788): Enable Chrome settings sync for this extension!!!
  I love this extension, but every time I set up a new machine and install it I shudder because my whitelist doesn't sync so I've got tons of pages I open end up getting auto closed because I didn't update the whitelist to protect them.
