Does what it says

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

It's compatible in newer version and work like a pro!

Nice addon but it has some issues that were reported on github like a month ago and the dev did not give any response yet.

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 :(

Didn't work the first time. Had remove and reinstall it.

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.

Pros :
- save indeed tabs in sets/groups

Cons :
- when many tabs in one group, scrolling through tabs has a displaying bug for several seconds which is very annoying
- doesn't automatically add new tab to (or delete closed tab from) a current/active group
- "group view" can display tabs by expanding (which is good), but tabs are displayed with their URL, when tab name would be preferred
- click on a tab link opens a new tab even if the link is already open, resulting in duplicate tabs if doing so
- switch between tab groups will open new windows, resulting in duplicate windows
- there is a bug for the "add current tab to TabSet" option, the same tab is always added

Remove Tabset button inactive
After losing Tab Mix Plus in Firefox 57, this is a useful supplement (have to load other addons as well to recreate the (Tab Mix functions)

Only problem thus far, is that the "Remove Tabset" does not remove the tabset :-(

Excuse me - I am stupid :)

Really like it, but with a grey-based theme installed, the icon is almost invisible. Any chance of offering a choice of colours?

Could you add the possibility to remove some urls from group?

Put the delete "X" button on the left of the "open" maybe so that it doens't accidentally get clicked on.

If you want to delete your extension fine....i think its a good one...just needs a bit of tweaking that's all :)

If you delete there are many tabs extensions waiting for the 57 Firefox after beta to get into the game
