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.

I can't browse the internet without this extension. It's very useful and reassuring...

best one, helpful

My most used extention, together with Darkreader. Absolutely love it.

this extensions is the reason why i make Firefox as my default browser after 12 years apart

excelente, al sincronizar no se sincroniza todo

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.
