Basic functions work: in management mode, drag & drop one tab list item to another group; switch to group. The biggest problem is memory usage after long time usage of Firefox v 143 on a Mac Tahoe (not sure of other OS). The memory usage jumped from around 1GB to 7GB after upgrading MacOS to Tahoe version. In the background, must be keeping other OLD tabs in groups already closed but still open (not sure contents of pages already loaded). When I disabled this extension, suddenly more than 20 tabs popped out when total opened tab in all groups were about 7. Plus, Firefox now has implemented tab grouping feature same as Chrome: to collapse tabs into 1 group tab.

Very easy way to decrease the number of open tabs.

It was good extension, but today all my tabs in groups are gone (except main group). And i have no backups to restore

i keep having issues with previous session not opening, and normally i can just click "restore previous session" and it returns all the tabs to the correct groups but i had a guy clean my pc today and he didn't restore session before closing and reopening again (which makes the option dissapear). which left me with "reopen all tabs" in recently closed, and not only did it not restore them all, they were not in groups after restoring. well, the extension only made the experience slightly worse but i needed somewhere to vent i guess lol. becareful out there if you cherish your tabs

覺得不好用移除結果卡個垃圾不知道怎麼弄掉

Unfortunately no longer working with Floorp browser version 142.0.1@12.1.2
Waiting for an Update

Simply the best tab manager these days. Have used it since release without issues.

I originally gave this 5 stars, but as time went by it got more and more erratic. Maybe because I had many tabs open?
More and more often, large numbers of tabs would vanish; sometimes several groups would lose most of their tabs. I could usually get most of them back from the backups, but the tabs I had added within the last day would not come back.

Fantastic extension. Makes managing tabs and tab groups a breeze. A few issues:

1. The extension makes backups in my download folder, which is not great since I like to keep my downloads folder clean.
2. Does not yet play well with the new in-built tab grouping feature from Firefox. Hoping this will be resolved soon.
3. The black icon color blends in with my black window color, which makes it nearly impossible to see the button.
4. On first install, the existing tabs don't integrate with the extension and need to be manually moved in.

Those aside, It's such a great extension, easily one of my favourites. Thanks!

Best Tabs extension.
Would rate 5, but after the latest Firefox update, the tabs that are not in a group, are not visible at the extension, unless you add them to a group.
So, if you open a new ungrouped tab and close out of Firefox, it disappears, since it is hidden and it is not in a group.
Also, when you close out of Firefox, some tabs, sometimes gets ungrouped, and since you cannot see ungrouped tabs anymore, you got to find them from Firefox's drop down menu, since they are hidden.

Looks promising, but does not support pinned tabs.
