It is extremely useful, stable, easy to use.
I have been using it for four years now without any problems.
It can also create backups, which take almost no storage space.
Also fully open source and recommended by Firefox :)

Before this plugin, it was a mess to manage different windows between different contexts. Thank you for developing this fantastic extension!

cool

This is what I needed from many years ago and finally I found it!

The most necessary extension for Firefox. It works very well until version 86.0.1, but it is "breaking" in version 87, consuming all the memory and crashing the browser. Even so, I prefer to use the old version of the browser and keep the add-on installed, but correct that, please, I would be very happy. Congratulations to the developers!

Brilliant add-on. This is as close as I've come to Opera's workspaces (which I loved). This is even better though, as it combines grouped tabs with Firefox's containers. Also, if you're concerned that switching between groups is not just closing the current group's tabs and re-loading the selected group's tabs, then don't worry. They just show/hide tabs as you select different groups which is exactly what I wanted!

Please port this over to chrome..... I desperately need this on my brave-browser :/

This extension is just plain awesome! :-) Together with the "Tab Center Reborn" extension managing a huge amount of tabs is just pleasure. At first it takes a little bit to get used to it but after a while it's really fun. Many thanks for that great extension!
