Today the extension somehow lost track of all the tabs in my groups (~50 tabs). I just had to restore an automatic backup created by the extension to fix the issue.

Bugs will always be there, good software makes them a lot less annoying.

Keep up the good work!

This extension is so pleasant to use.
Thank's !

really nice

Very buggy.
Tabs were duplicated a LOT, clicking on a tab duplicated it. Opening a new tab group created multiples of every tab.
Not fit for purpose.

Coming from Opera, this add-on is a godsend for an alternative to workspaces, functioning just as you'd expect. It isn't without its minor flaws, though: When clicking the icon for the extension, it always opens up the list of tabs in the current group first, forcing an additional click to see the list of groups. The only benefit you get that isn't already on the top of the Firefox window is quicker access to customizing the current group, which is way less useful than quickly changing which group you're in, the main point of the add-on. Plus, the icons you can set for groups are very limited in design, and it seems weird that you can't at least use the icons for containers. But again, this add-on performs flawlessly and helps productivity immensely, so I still recommend it.

Overall helpful, but with a massive flaw in that it randomly moves tabs out of their groups and into the "other tabs" section. Will often do this in the middle of browsing, not even on startup. What's the point of an extension for organizing tabs if it deletes your organization at random? Just a few minutes ago it moved over 60% of my tabs out of their groups and into the "other tabs" section.

I wish I knew this add-on existed before. I cannot do without it anymore. Exactly what I needed, great design, and free!
On of my essential add-on now.

Worst. Extension. Ever. Arbitrarily deletes tabs with no warning and no option for recovery.

This add -on is great but either does not work at all or after some time - this is how it is impossible to work - please improve - help me

Great add-on and a very good organizer. Even better than similar features in Chrome or Edge.

100% CPU usage

It's good extension but when it has big bug: sometimes tabs in one of the group are duplicated during browser restart.
Update: very stupid and annoying bug, I did reopened the browser 6-7 times and now I have 100 tabs in my Work group. It's so buggy. Can't use it anymore.
