I have used this for add-on for quite a number of years, have never experienced any problems, and appreciate the role that it plays (with the Facebook-container package as well). Lastly, as an add-on it's been vetted by Firefox, which should be another layer of correctness and security for the code.

Common your synchronization are shit, i lost all my open default sites switching between Floorp and Firefox, in firefox lost all my custom containers and data (in floorp are ok, but cannot restore in firefox)

Absolutely invaluable

Very powerful & useful addon.

It's nice, but, can we have an option to open a site in 'no container' by default?
