Un po' macchinoso, ma buono!

This is so useful to keep your cookies and accounts separated and a really nice and clever way to stop some tracking.

the best extension - why I need to searching it and it's not in default distribution!?

good app thx guys

Very useful extensions, especially when you have multiple accounts on a site and don't want to constantly log in or out or when you just don't want a site to access data from other sites you visit on your main profile.

This is one of the core plugins I use (in addition to Ublock Origin).

With the account sync, containers are also remembered across different computers as well, so I don't have to set up the containers on every new laptop or reinstall of firefox. Sometimes I mistakenly open a website in the wrong container because I don't always map every single website to a container, but most of the time it's a non-issue.

I'm surprised this is still an add-on and not a core Firefox feature.
