Very useful for maintaining multiple profiles/accounts on websites.

It's really a nice extension that I was looking from long time
There is an issue when firefox closed by system ( Windows ) It did keep the current tabs but removes the tag ( container ) from it - to be like normal tab without container
It would be nice if we could send the link or page to specific container without opening it or opining all tabs of that container
Thanks

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 :)
