As soon as the extension is deactivated, almost all data is erased! There is no way to recover anything and you cannot make a backup! This makes it INUSABLE. This is a very serious problem that has never been solved!!! Why don't you use Firefox Sync?

Amazing addon, I use it every day.

Really useful, now i need it for the android app

Much appreciated to have this option. Love it to keep google out of my other tabs but youtube :)

Couldn't live without it. Only thing that would be better is a system context menu to target containers when clicking links in other sources.

This is a must have extension, and it makes Firefox very awesome.

This is a killer feature! No need for separate profiles/browsers and the headache of managing them.

Really useful! As other said, with this extension, it's easier than ever to manage multiple accounts and be able to use firefox in multiple settings. I highly recommend using containers in combination with simple-tab-groups.

I had been using other browsers at work like edge chromium and chrome and using firefox for my personal / internet research. This is exactly what i was looking for, something that would allow me to consolidate to just Firefox and separate work from personal and everything else.
