A few years ago Firefox had Simple Tabbed Groups (it was wonderful) and then Mozilla changed the Firefox code to be modern/more secure but it ended Add-ons like the old Tabbed Groups. That upset me I lost 4-5 tabbed groups with a total 81 links, just gone. Over the years I looked in the Add-ons for a replacement for Simple Tabbed Groups but nothing until recently. I looked at this Add-on and I said No, it can't be, but yes it is. I do not know if it is the same coder but thank you. I've got 3 groups and growing.

Actually an awesome extension ^^ Managing groups is a breeze, and I love that there are options to play with in case I need a little more granularity. Thanks to the dev for making this possible!

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

Da ich stänig irgendwelche tabs auf habe, sehr nützlich

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.

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.

Needs to be more smooth.
