It could be better if there is an option to move the old tab to where the new tab would have been. Currently if you open hundreds of tabs and the old tab is in the front of the tabs, the tab bar will move all the way there, which is not good.

Reply:
I find out that if "On remaining tab" is set to "default tab behavior", the old tab will be moved to the new place, which is what I need.
Thanks for your response!

The problem is that there are cases when all duplicate tabs are closed without keeping neither of them or both
-auto-close on
-no filters
-keep newer tab (keep tab with HTTPS, keep pinned tab)
-scope: active window

The situation occurs when both tabs were loading simultaneous!

ok

Simple yet customize-able interface does the job.
Filters provide even more advanced options.

Feature request:
Don't show the badge and number when there is no duplicated tab.

Very good but has a bug:
By applying filters for ignoring both "hash part" and "search part" it will not work for duplicate tabs that have only "hash part".
For example for the following URLs one time apply only "ignore hash part filter" and another time apply both "ignore hash part filter" and "ignore search part filter".

Sooo good! Taming my 99 tabs with gdocs, things to read and random assortment!

This is super useful extension. I use it a lot.

Some suggestions for improvements:

* Allow possibility to "ignore" some open tab so it's not taken into consideration when checking for duplicates.
I had one or two situations when it would be useful (filters we not enough).

So for example when you have "duplicate tabs" list you could right click and choose "Ignore duplicate checking for this tab" (or some other better text) and this entry on "duplicate list" would get different colour or be in italic to indicate that we ignored this page. We could then click again and uncheck this option.
When tab is ignored then we don't see number that we have duplicate for it and "Close all duplicate tabs" won't close this tab.
* I have no idea what this "pin" do on different option sections ("Priority", "Filter", etc). Maybe have some hover over text that explain what it does
* Make this extension open source - this is of course you personal choice to keep it private. I just think it would be awesome and help improving this great extension even more.

This is really handy and has a good set of options for fitting into whatever way you like to browse. You should absolutely give this a try, and open the options panel if it doesn't suit you out-of-the-box.

The one extra thing I'd like to see is an option to have settings like "ignore path" apply to particular domains only -- I'd love to be able to open four articles from the same website but reliably collapse four instances of the same web-app.

Wer sehr viele Tabs offen hat, verliert schon gern mal den Überblick und es können Seiten doppelt geöffnet sein.
Mit diesem Addon ist damit Schluss. Danke ;-)

Hey mate, nice add-on! I got the hint in the Git for Simple Tab Groups (https://github.com/drive4ik/simple-tab-groups) from an other user while asking there for a feature doing what your add-on is doing! .. and now: tataa, my problem is solved. And what i real like is the quick change of the options in the menue ... this add-on has all i need ... btw. i realy love the design! ;-) ... its a litte "ghostery "-like :-D ..

Nice add-on. Works well. A minor issue. When there are multiple pin tabs with the same URL, this add-on closes the oldest pin tab.. It need to close the latest pin tab. If you could fix this, it would be great.

Super extension overall, but there is a bug in the settings handling for filters.
If "Ignore search part..." is set, then "Ignore hash part ..." isn't doing anything. Similarly of "Ignore path part ..." is set then the two other settings are useless.

This is due to "else if" being used in areMatchingURL function from urlUtils.js (line 24, 28). Switching this to independent ifs allows to respect all settings (and support urls having both hash and search signs.

If possible please bring a fix for this one (I can provide a pull request if the code is on some git repo).
Thanks in advance.

Interesting. But bad design.

Love the extension! If there's any way to enable blocking multiple tabs from the same domain/subdomain (just for specific domains) that would be really really useful to me. Thanks

Hey ever since the latest update if you have the addon automatically close the duplicate tab and "On remaining tab" activate, this no longer works. It still closes the new duplicate tab but it no longer switches to the old one.

since Fire Quantum, no longer shows mini-window indicating duplicate tabs.

Fantastic! I wish I could also remove EMPTY (blank) tabs as well beside that: reliable, perfect!
