I find the app excellent and effective, but I would also like to signal that, when synching from a different Firefox browser operating in another language, the basic containers like work and bank were duplicated for the two languages, and that should be fixed. Keep up the good work!

the best firefox feature ever

This extension is one of the main reasons I use Firefox.

Es de las mejores ideas que he visto en años. Muy bien hecho!

Excellent now that some bugs are gone :-)

Sangat membantu Penguasa Akun. Mantap.

Must-have add-on for Fire-fox

Another MUST HAVE extension for me. I don't want websites checking every other website I ever visited. So I gave them all a container to live in.

This is less important now that FireFox offers Cookie Isolation in Privacy settings, but it's still useful as it allows me to have multiple different accounts logged in for the same website at the same time.

each new device integrated in Firefox Sync BROKES EVERY CONTAINER PARAMETERS I HAD!! This plug-in is crap!!!
