Very good extension, but it have a very big bug:
When you delete an group, all tabs from all groups are remove.

very ugly user interface, barely usable

Add-on suddenly stopped working, which was quite a disappointment.

Legit kept hiding my taps and I couldn't make groups show on the tab list

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...

Keeps loosing my tabs when I close firefox.

Become one of my favorite extensions!

Its nothing Simple. The using give no effects. I'am nowhere see groups.

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

First time using. Had two separate FF 136.0.4 (64-bit) instances open with multiple tabs on Win 10 Pro, up-to-date.

Created a new group, made a typo and deleted the empty group. The main instance containing the tabs (over 30) I wanted to group closed and isn't recoverable, two days of research down the drain.

And now I need to find an alternative.

Not clear how to use. needs better instructions

Would love if we could sync tab groups easily. Besides a backup. Perhaps some way to sync with Git?

A good tool for organisation on the firefox browser

adding a tab to a group closes out all other tabs in window. idk if that's expected but incredibly unhelpful.
