★ On remaining tab options (used with "Close tab automatically):
- Do nothing (default): nothing is done after the duplicate tab is closed.
- Activate: once the duplicate tab is closed, the remaining tab is activated.
- Apply opening tab behavior: once the duplicate tab is closed, depending on the default tab behavior, the remaining tab will be moved to the position of the closed tab and activated if needed.

Duplicate tabs detected will be notified in badge.

- Keep tab with https (default on): Ignore the scheme part during comparison and keep the tab with the https scheme.
- Keep pinned tab (default on): Keep the pinned tab.
★ Filters options:
- Ignore hash part in URL (default off): for instance https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer/#detail-relnotes and https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer will be considered as the same URL.
- Ignore search part in URL (default off): for instance https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer/?src=ss and https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer will be considered as the same URL.
- Ignore path part in URL (default off): for instance https://addons.mozilla.org/en-US/developers and https://addons.mozilla.org/en-US/firefox/addon/duplicate-tabs-closer will be considered as the same URL.
- Compare with tab title (default off): If the URL doesn't match then compare using the tab title.
★ Scope options:
- Active window (default): only closes/displays duplicate tabs that belong to a same window.
- All window: closes/displays duplicate tabs for all windows.
★ Hotkey:
- Alt+Shift+W to close all duplicate tabs (this could be configured in the options in future version)

- (2025-06-13) Thiarlao Bonitão: Very very VERY Useful.Best tool for duplicate tabs!
- (2025-03-20) Chanmax Coco (jesus2099): I don't have MozillaZine account to report this but Google says "This extension may soon no longer be supported Remove or replace it with similar extensions from the Chrome Web Store" There might need a migration to Manifest version 3 (MV3). And also I wanted to report this BUG : Ctrl+U view-source:URL is seen as a duplicate of URL.
- (2025-02-15) Jon Schlinkert: Great extension! Very reliable, thanks! One request... please add an option to ignore "New" tabs. I sometimes keep multiple windows open, and I open a new tab when then window isn't focused. This prevents (some) open tabs from automatically "doing stuff", like autoplaying videos if I have a youtube video open.
- (2024-09-23) *: Works for me.
- (2024-09-21) Vishnu Agarwal: certainly good as used for years, however org has blocked this citing Security risk
- (2024-08-08) Mateo Jajkowski: I love this extension for Google Chrome. Makes my life as a web ops engineer much easier as I always have 5 million tabs open.
- (2024-07-30) Grzegorz Skoczylas: I have tried several similar extensions. I think this is the best. I hope Google will not take it down.
- (2024-06-15) David Martin: Working great for me; extremely useful! Thanks!
- (2024-05-18) Royce Benda: Was working great for the longest time but currently there is an issue where it will automatically close any search result from Bing.
- (2024-01-23) Elizabeth Lomax-Laidlaw: Working fine
- (2023-11-29) Inna Inna: BEST!!!
- (2023-10-23) esgalmir: generally it works, but desperately needs an update. some settings broken... sometimes closes wrong duplicate (newest, not oldest, despite of settings) or opens wrong tab. sometimes not detecting any duplicates. sometimes closes a tab that is NOT A DUPLICATE altogether (i.e. does not allowing to open some specific URLs).

- (2023-09-13) tek marvel: works great when it work. often does not notice there are duplicate tabs, requiring chrome to be restarted for duplicate tabs closer to start working again.

- (2023-08-06) josh wanner: Need better instructions. I'm having difficulty whitelisting google and images, not sure what to do to whitelist it, not working. 5 stars for better instructions. Docked a star for unclear instructions.

- (2023-07-08) COW KING (THE COW KING): fairly good. one annoying bug, it will jump to one of the duplicated tabs instead of staying on the starting tab, making it unusable

- (2023-06-03) Samuele gg: Una delle migliori che abbia provato per eliminare le schede duplicate, presente anche il contatore sull'icona che è ben visibile sulla barra. One of the best I've tried to eliminate duplicate tabs, also has the counter on the icon which is clearly visible on the bar.
- (2023-03-21) Gabriela: Thanks for making this! It's been my go-to extension for finding duplicate tabs. I've noticed however it's not handing well one of the following (still trying to figure out which): a bigger amount of tabs, tabs that go into sleep mode, or tab grouping.

- (2023-02-07) やまよし: It's a great app and it stands out among the current applications with similar functionality. However, I have one technical request. You are currently implementing a whitelist, but is it difficult to implement a blacklist? In fact, there are more sites that don't want you to do anything, so it's a bit troublesome to register them in the whitelist each time.

- (2023-01-27) Dr.Ne0Gen3tic (Forensic Buro of Quantum): the best I could find! But how do I come to the conclusion? Now there are the "matching rules," which allow different "cases" of matches. With some pages, you want to ignore the exact "title" or the "search part" in a URL. Or have only the titles been compared? This is easily possible here, and there is absolutely no problem! In addition, "HTTPS" can be compared, and they close the tabs only when prompted, so I have full control at all times! So this extension is EXACTLY the extension that I was looking for! In my opinion, this is the best extension of this kind that I have found "so far"!

- (2022-08-16) Peter Kionga-Kamau: OMG it is SO SLOW. I've been sitting here for two minutes waiting for this thing to close 18 tabs. What the **** is taking it so long?!

- (2022-08-15) Mr. Spectacals: Already loving it. I surf a lot so this will be helpful in removing duplicate tabs.

- (2022-07-23) Daisuke: Good. But it would be even better if the whitelist worked for cases other than the decision to automatically close tabs. (ex.) "Duplicated tabs" list, "Close all" button behavior.

- (2022-05-18) Victor Januario: Great extension. Thanks. A suggestion for those that prefer to Blacklist URLs, enter this in the Whitelisted URLs box: For one site: ^(?!.*example.com).*$ For two sites: ^(?!.*(first.example.com|second.example.com)).*$ For three sites: ^(?!.*(first.example.com|second.example.com|third.example.com)).*$ ... and so on.

- (2022-04-18) The Great Scott: Been using on Chrome for a while, finally had it with excessive dumb nanny resrouce hungry thing and moved fully to Opera GX Installed hassle free, manually set the intuitive and easily interpretted options, badaboom. Works seemlessly as expected, namely if "power browsing", any replicant tabs simply never appear. You can fine tune the entire thing to, for example if you are opening POSITIONS (#ref) on a large document page, to KEEP them, while still blocking exact same requests (default would be to not). Great stuff, an essential and suprisingly not standard tool. -Nice one Dev Fairy-

- (2021-07-16) Ifer30: Having a problem where even if a site is whitelisted it still treats the tabs as duplicates, even when they have different urls.
