Does what it says

great tool it save me time and it keep my PC running cooler

Better than other tab "managers". UI is simple & clean

Was using another extension to save tabs prior to Firefox 57. Tried Tab Saver and so far it's working just fine.

Is awesome. Simple and do exactly what I need. Save tab then restore when I need. Thank you. :)

It was so good in black theme... But now there's no switch, it just matches the FF theme, it's a shame :(

This is the only extension that allowed me to transfer all my open tabs from one browser version of firefox to my developer version. All other attempts using different methods of builtin browser functionality failed to work, all other addons i tried also failed or lacked the ability to do so. Finally, thank you so much for a truly great addon.

Excuse me - I am stupid :)

A great replacement for the legacy Tab Groups

Excellent, this is the only web extension that works ok as a Tab Groups replacement, the only think I need is ability to sort the tab set list.

If you need to save tabs/sessions between restarts (very useful if your work involves the use of multiple tabs) this extension is fantastic.

It's not quite a session manager (but it doesn't claim to be) because you can't automatically save/delete sessions, but very helpful nonetheless.

Yes, precisely! I mean that, instead of having to click a button to see the tab sets, the tab set names could be always visible on-screen in the browser for easy selection (like a bookmarks bar, as you say).
