It's good. Some suggestion: Please put the new created group on the top since we want to use the new group frequently.

Overly complicated – too many preferences. Doesn't work as advertised. "Create new group" dumps you in the preferences with no clear way forward. Breaks the "Add-ons and Themes" item under the "Tools" menu. Don't install.

Da ich stänig irgendwelche tabs auf habe, sehr nützlich

Despite what some people say, this extension is very easy to use and simple and has worked flawlessly for years and it is still working and almost bug-free.
But is it still relevant after Mozilla updated the "Firefox multi-account containers" extension 6 days ago (Oct 25, 2023)? Is there a feature comparison somewhere?

This is exactly what I needed all these years. Finally I don't have a constant mess of dozens of tabs and multiple windows taking up taskbar space. It's so much easier to keep track of everything now. I put the addon button in the upper-left corner, replacing the default Firefox button, stylized it with custom CSS, and now it's perfect.

This is less "simple tab groups", and more "complex tab and window organisation". I think the extension is let down both by its name, and by various articles that claim it offers similar functionality to chrome's tab grouping. It's also relatively unintuitive to use.

Amazing addon, absolute time and lifesaver when reinstalling the OS or if you love having a lot of tabs but hate the clutter. if there was one feature I wished it had it would be setting a custom backup path as my download folder isn't backed up and goes along with my previous OS during reinstall.

Looks cool, love the idea... but it backs itself up to a random location that I can't seem to change, likely won't use it until this is fixed.

Needs to be more smooth.

Why are so many permissions needed for this tab manager? There should be more optional permissions. Other tab managers work well without requiring (for example):
"(Access your data for all websites): for tab thumbnails and catch/move/reopen tabs in needed containers/groups" or
"downloads: for creating auto backups"

My favorite tab grouping option for FF
