Very thoughtful add that makes my job much easier

Great extension for vertical tabs. Works flawlessly, no bugs and no crappy animations like other extensions I tested. Grouping tabs by right-clicking is super useful, it's like bookmarks but better. Speaking of bookmarks, you can select tabs and bookmark all of them at once, super useful. The sections, used with Firefox Containers, are super great to separate work, school, and personal things. Unloading tabs is also a functionality that I think is super useful when you want to keep tabs in the sidebar but don't have them loaded.

Nice! Thanks!

Please add ( i created an account for just this review as its so glaringly obvious an option) the default option when opening the sidebar to be "bookmarks" not "tabs" as mentioned by others. Its a bookmark addon primarily. Let me use it as such. The option to remove unneeded "other bookmarks" and "bookmarks menu" would also help the user experience.

So much more responsive and performant than Tree Style Tab (aka TST) if you have way too many tabs open. This is the one you want.

Perfect

I really don't know how I lived without it before.

Looking for something much, much simpler to use. All I want to do is to quickly group tabs.

Make setting for default panel (bookmars or tabs or ...). I need bookmarks, but it allways open tabs first.

Excellent extension. So much more than just vertical tabs. Panels can be configured to match containers.

Would highly recommend.
