Excellent!
Not perfect but very powerful.
Having now 1300+ tabs, and trying to clean up,
I could close dups much easily than before.

Some caveats thought:
1) compatibility with Sidebery (groups are seen as duplicates)
2) containers handling (because of Sidebery ?) are not recognized
3) it took me a while to understand that the numbers in brackets where refeering to a window id. I am using Window Tiler to given them a name.
A documentation would help.

This was my go to tab manager since I have hundreds of tabs open and I'm afraid to simply close all of them, but also lazy to review them one by one.

Wow! Top!

Please add menu or button to close all tabs with the same domain or the same filter string. Really cicking "x" one by one is boring and takes long when I have >2k tabs open

I use this addons lot of time and it is very usefully when someone like to have open lot of tabs.
But discover bug. When try use "Full View window" then have a new window on windows bar but this option dont show to me window.
Few weeks ago this work ok.

When scrolling through tabs, it scrolls more than one page at a time. How can I change this to only scroll one or three lines at a time? Thanks.

Once you try this tool you think OMG how could I live without it ?!
I appreciate mainly saving my time and preventing from opening duplicate tabs. Thank you Kevin !

SO it places All tabs to a Side Window List. Too Bad doesn't Separate which tabs are in different window. IT SHOWS ALL TABS IN THE SIDE BAR.

Can't see the list of Closed Tabs &　can't Remove the Close TAB button from accidental select.

I made an account just to review this and say thank you. I saw you got a lot of negative bustle from some people. Just wanted to let you know I love this and use it often.

If I had one request, if you are still active with this project, is to allow the Full View to drop back like any other window. Small thing and personal to me I am sure lol.

Again thank you this is amazing.

It works more stable than tree tab viewers.
But for several thousand tabs there is a few seconds delay even for several recent tabs.
Also, for sidebar mouse wheel minimum move scrolls several pages instead of only one page.

The faster it boils, the faster it cools. There were too many useless features, and it seems like burnout came in the end. I've seen many cases like this.

This extension is indispensable. I use it everyday all day long and require it to keep my work organized. There is no other extension that works this well, is this reliable and provides this exceptional capability. Use it and you will see the same.

I have been using this addon for quite sometime now, and love it so so much. I would be totally lost in all the sea of tabs I keep opening without this.

It has almost everything needed to manage hundreds and even thousands of tabs. The one other thing I would love to see is an indicator showing which tabs are currently playing audio, kinda like with the native firefox drop down list of tabs. Still, an amazingly feature rich and useful addon. Thank you so much.

Works nicely, WHEN IT WORKS (Mac). Unfortunately, keeps losing the renamed Windows. Seems to occur if you disable the extension and re-enable it.

Too bad this extension is no longer maintained.

It is nice to use!
