Image from store Clutter Free - Prevent duplicate tabs
Description from store ** Automatically detect and close duplicate tabs Preventing and closing duplicates tabs is the core mission. The extension runs in the background, checking when tabs are opened or links are clicked to see whether the target webpage is already open. If open, the extension switches focus to the existing tab, instead of opening a duplicate. NEW: Quick Tab Search - search, switch to and close tabs. (Similar to ‘Go to tab’) NEW: List all duplicate tabs, close them directly from list. (For supporters only initially) Tune the core functionality using options - add websites or domains to allow-list to allow duplicates, or use the block-list to only block duplicates on certain websites. ------------------- OTHER FEATURES: 1. Quick Tab Search (Ctrl/Command + Shift + L) - Search and switch to tabs across Chrome windows - Close, duplicate, allow-list, or move tab to new window - Keyboard shortcuts for all common actions - search, select, switch, close tabs (more coming soon) 2. Direct Switch - ClutterFree highlights links on webpages that are already open in another tab. Clicking a highlighted link switches directly the tab where the link is already open. 3. Open tab count - See number of open tabs on extension button 4. List duplicate tabs (e.g. in switched-off mode, or after installing) - Close all duplicates with a direct click - Selectively close duplicates - Original tabs marked with a special icon 5. Keyboard shortcuts and right-click menu options for quick actions: - Open extension window, - Duplicate current tab, - Move a tab to the end, - Add page to allow-list, and more 6. Detects duplicates suspended by 'The Great Suspender' extension 7. Search tabs from address bar - type `cf` and space to search, and switch to open tabs 8. Detect all pre-existing duplicates, and prompt to close them 9. No analytics or tracking, including Google Analytics 10. Export and import settings to file - to set up different Chrome profiles to same settings 11. Periodic statistics on duplicates prevented, and top domains for duplicates ------------------- PERMISSIONS >> "Read and change all your data on the websites you visit" This phrase above is how Chrome describes when an extension uses the 'tabs' and "all_sites" permissions. The extension needs these permissions to manage tabs - checking for, preventing, and closing duplicates. You may read more about 'tabs' permissions here: https://developer.chrome.com/extensions/tabs ------------------- UPDATES (Full update notes: https://updatenotes.blog/category/clutterfree/ ) UPDATE 17 Jul 2020: - Ignore hash and ignore query, on all websites, are out of experimental features - Advanced URL management (Supporters only) - Ignore hash and ignore query for selected websites UPDATE 14 Jul 2020: - Show all tabs from same domain as current tab - from keyboard shortcut, right-click menu, or search window - Close all tabs from same domain as current tab (Supporters only) - from keyboard shortcut or right-click menu UPDATE 10 Jul 2020: Customisable keyboard shortcut actions - Choose from more than a dozen actions - Supporters only - Five pre-defined shortcuts for non-supporters UPDATE 07 Jul 2020: Tab Search window updates - Copy all tabs to clipboard - Move tabs - to end or start of window - Pin/un-pin tabs (Supporters only) UPDATE 06 Jul 2020: All users: - Option to ignore query parameter when comparing duplicates (?a=b...) Supporters only: - Suspend and unsuspend tabs from tab search (uses The Great Suspender extension) - Search for suspended / unsuspended tabs with 'is:suspended' UPDATE 03 Jul 2020: - Added allow list and block list options, replacing whitelist - Domain block list is out of experimental features, available only to supporters - Other minor bug fixes and updates UPDATE 29 Apr 2020: - Added 'System theme' option for extension window - Extension window themes are now available to all users - Minor fixes and code updates UPDATE 03 Jul 2019: Building on update from 10 May (below): When a link redirects to a previously open tab, the duplicate tab returns to previous tab before closing. This allows Chrome's 'Reopen closed tab' shortcut action to work as usual. Thanks to Joakim Nilsson for the suggestion. In a future update, this will become default behaviour: On clicking a link that is already open, the source tab will close. It will go back to the previous page before closing if the duplicate URL is after automatic redirection. Currently this behaviour is in advanced settings.

New: Option to close source tab when clicking a duplicate link (available under advanced settings) 2. Updates to supporter tiers 3. Bug fixes UPDATE 4 Mar 2019: Settings export/import & more 1.

Bug Fix: Check target tab URL before switching (to prevent direct switch to obsolete tabs) UPDATE 29 Jan 2019: Bug fixes & minor updates 1. Bug Fix: Redirect loops caused when opening same document again from drive.google.com 2. Renamed extension on/off state as ‘active’ and ‘passive’ states 3. Tab search popup opens in the same size and location where last closed 4.

Red dot to indicate all duplicates - including those created using the Clutter Free menu or keyboard shortcut (alt + shift + d) 3. Updates to notifications, including option to disable the 'Duplicate tabs found' notification UPDATE 10 Dec 2018: Duplicate tabs - indicator & lists 1. A red dot on extension button to indicate that duplicate tabs are open 2. See list of open duplicate tabs, and close all or selectively (For supporters only till mid-Jan 2019) UPDATE 5 Dec 2018: Supporter subscriptions & context menu update 1. Gift a small subscription to support continued development of Clutter Free 2. Shorter menu item name when multiple context menus are added - now it just says 'Clutter Free' UPDATE 22 Nov 2018: Notifications upgraded 1.

  • (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.
  • (2019-11-29) Ringo Seven: Worked for about 2 days then stopped. No clue as to why but it says there are no duplicates. I was using this for app development and debugging but now it's useless. Lots of other people reporting the same issue. Was using the latest version as of 11/28/2018. Will look for a working alternative.
  • (2019-11-27) xiaopenger liu: 清楚的看到打开了几个标签,很好的插件。
  • (2019-11-01) Heph Adams: It kept me from reopening (and losing track of) 80 github tabs this week!
  • (2019-10-21) Adrian Staicu: It works, BUT it can't handle 1000+ of tabs. Chrome froze for about 4 minutes after install. I managed to open the duplicate tabs window and close a few tabs but it took a lot of time to update the list. Overall nice UI. And maybe it works better with less tabs.
  • (2019-10-15) tomek szmuk: noice you could add history check so it woudnt open url if it already has been opened before
  • (2019-10-08) QUI SA: Thanks search tab : hover switch ,delay too long
  • (2019-09-25) L Guaire: Does exactly what I need, which is that every time I deploy to desktop from NSBasic, it removes the prev tab. PERFECT.
  • (2019-09-17) 罗宾: 正是我需要的, 我喜欢
  • (2019-09-15) Sebastian Jurk: Kills tabs open somewhere in the browser just because I open the same page again and want to create a different account. Now I have to search where the tab vanished. Also after a quick check there is no easily recognizable option to disable this nonsense. Will deinstall now.
  • (2019-09-06) Schuyler Rice: The fact that the "white list" rarely works properly makes this extension EXTREMELY annoying to deal with. Pages can clearly be listed multiple times in the white list and even URLs with similar or even EXACT duplicate formatting are closed... so the white list functionality is BADLY broken and needs to be fixed immediately for this extension to not be... well... kind of bad.
  • (2019-08-10) Andrew Thiyam: I tested this on Amazon with about 10 duplicate Amazon product listing pages opened. It only could detect a few. I like all the features except it doesn't do what it's meant to do. If the developer knows a workaround, kindly respond.
  • (2019-06-01) Chris s: Instantly got a desktop popup upon installing and immediately uninstalled this extension.
  • (2019-05-28) Joakim: This is now my favorite extension after adblock. 99.9% of the time you won't notice that it's there, it will just sit in the background and clean up your mess. Even when I only have a few tabs open, this extension will sometimes clean up duplicates for me. When I have 10+ tabs open it provides a significant productivity boost. I recommend skimming through the settings page though - there were a few things I didn't like, and I was able to fix all of them by changing the settings.
  • (2019-05-16) Chunlin Li: That's the tool I am looking for. It's extremely useful for me who open hundreds of taps.
  • (2019-05-03) Mark Gemmell: It's good. It simple and works and helps my browser and brain stay a bit more streamlined.
  • (2019-04-27) Ali Douiyek: For some reason, recently it stopped working in private mode. It does detect the duplicate private tabs, but doesn't close them. I did enable the extension in private mode, and allowed access to the urls. Works well in normal tabs.
  • (2019-04-04) Prabhash Singh: Feature Request: Please add feature to close all tabs open for current tabs domain name. Additionally it would be really good to have option to choose opting out from closing subdomain variants.
  • (2019-01-28) Nguyen Pham: tot
  • (2019-01-13) Maxi Ostrower: Perfect, it does what I need
  • (2019-01-10) Ted G: Im giving this one star because a chrome extension wanting me to sign up for a paid subscription is absolutely and utterly ridiculous. If it had asked me to donate like $5 for all features forever I would not had minded but a FREAKING SUBSCRIPTION for this??? Ya Right.
  • (2019-01-06) Ɗσραмєαη єѕcσвαя σтмιc: One of the developers (I think) replied to my old post and informed me that it's been updated so all notification options could be selected. And I really needed that! I tried some other extensions with similar functions but none of them are as efficient or customizable enough to fit my particular needs as Clutter is so I was really hurting to use this extension again. So thank you to the developer(s) for your attention and your hard work. This is my favorite extension in the web store because even though it's not really something I see all the time, it's the one I utilize the most by far. **previous review** This extension worked best until the most recent update. I don't want the app's notifications on when it closes dupes, but there's no option to turn it off. The option to switch to Chrome's notifications doesn't even work and the notification will sit there until it's closed manually. Very annoying. Had to uninstall.
  • (2019-01-03) Ryan Douglas: It doesn't do what it says it will. I primarily got this extension to work with React development so that when a dev server is restarted, the browser will simply go to the currently open tab. It doesn't work (or give the option) if you want to blacklist a whole location (e.g. localhost: 3000). Additionally the extension prevents me from opening a new tab on my browser, although that could be due to my use of Momentum (which is good) as the default new tab. Also the little pop out tab manager is largely unnecessary and is made worse by its UI. Definitely needs some more work before it's useful.

  • (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) null void: 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: release) doesn't work for all URI's
    Doesn't detect trailing "/" and other URI prams.
  • (2016-08-29, v: 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: release) Iv She: ver
    ver after update have troubles in google docs (spreadsheets). Plugin redirects me to previous sheet when i navigate between them
  • (2016-05-20, v: release) 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.
