Incredible addon !! Simple UI , keybinds , saves your tabs progress into specific groups ( works like an autosave ) , open source, there is backup , you can open groups in different windows. Navigation may be troublesome.

It is incredible that Mozilla still recommends this addon. It used to work great, but since Firefox 132 it has some major issues. For me, first time it lost all groups when I installed Firefox 132 (31 Oct 2024). However, back then I managed to restore them via the addon’s setting. Then it lost them again on 10 Jan 2025 when I installed Firefox 134.

Now as others have reported, with Firefox 135, it is impossible to restore the groups via the addon’s settings. When you try to restore from a backup file, it simply closes the browser and when you open the browser again the groups are not there.

Do not waste your time with this addon.

What's going on, please provide a patch. It's very inconvenient.

Excellent

#labels are not supported. Mozilla should wake up and enter the 21st century!

I've lost all my tabs, this addon is a beyond stupid

Works very well! I find that I can re-access my tab groups when I exit my Firefox window and reopen it. Pretty good for something that has not been updated in more than two years!
