Tabs gone after Firefox close.
It happened right after all groups just deleted itself and all 100+ tabs were on main view.
BUT
I just noticed that this extension is making backups every day by default. Due to this, I was able to restore all of the lost tabs.

So am changing rating from 1/5 to 5/5.

That's literally what I need from such extension. Keep up the good work!

Please continue working on it. This add-on is much more convenient than the Chrome-inspired, brand-new built-in tab groups feature.

Please add an option to change the backup location

Works absolutely as expected, extremely useful to me, very happy with that extension.
Only one complaint: I want better control over the folder where backups are created! Because my Downloads folder is clogged with tens of STG folders of different versions...

Become one of my favorite extensions!

Simple and effective. Has a few integration shortcomings to my feeling, but nothing in the way of it being great.

A good tool for organisation on the firefox browser

Work well on 136.0. Thanks :)

Great stuff for organisation and keeping my RAM usage low, will keep using it until it breaks.

(Edited the bug report out because it turned out it was only an issue with librewolf specifically, no issues on waterfox)
