Great extension. I like to organize my tabs around subjects (Gaming, School, Personal, etc.) using this extension. With the added option to unload tabs from memory while not in use, this can make having dozens of tabs open more efficient and more practical.

would love if we could sign in to this extension and have groups sync across devices like a proper workspace

I've been using this addon for years. It's been great, but recently the feature to close tabs when switching groups to save RAM was removed from the settings. This feature was perhaps my favorite feature of this addon - if it were brought back, I'd give it five stars.

As an IT technician, I'm often switching between multiple tabs.
This add-on allows me to group tabs according to my customers, and simplify my day-to-day navigation.
A very useful feature of this addon is the ability to associate a group with a tab container: cookies are compartmentalized, so I can easily use several admin accounts on the same admin portal at the same time (several admin 365 accounts...).

this addon is ALMOST PERFECT. two things i'd love to see is the ability to SYNC TAB GROUPS across machines signed in to the same firefox account and the ability to SAVE PINNED TABS in a tab group. losing pinned tabs every time i forget and close a tab group is a real bummer.

Very powerful, easy to use, convenient. Great design!

Grouped tabs switching doesn't work when screen sharing is on during a google meet

Very useful for organizing my tab hoarding habit

Stumbled on a problem regarding this plugin’s internal mechanics: I can’t reliably use next-sibling combinators in my userChrome.css script because the tab list is interspliced with hidden tabs from other groups.
This could be fixed by making the plugin also sort/structure tab list group-by-group.
I understand that I’s a niche use case, but damn it’s annoying.

Used to love this. I have autobackup set up after a round a long time ago of it losing all my tabs. I don't save every single backup for space. My oldest is currently from last June. I've been saving tabs for projects, work, etc and when I tried to save one today it simply wouldn't respond. The majority of my tabs are gone and the groups empty. I'm not sure when it happened; even my oldest backup only has a couple of additional tabs to add. A lot of the newer things I added aren't there. I've lost tons of stuff. With backups, it never occurred to me I needed to check to make sure things were still there to even be backed up; my bad, I guess, for not going through every folder making sure every single thing is still where it's supposed to be at least weekly. Everything is simply erased.

My tab groups' tabs suddenly placed on one tab group! 664 tab groups into one. 400+ tabs missing!
