Très utile pour séparer différentes activités (notamment bancaires et commerciales) du reste de la navigation. D'autant plus que le paramétrage permet d'ouvrir systématiquement certains sites dans un container particulier

Best thing ever :)

Works as advertised, I can separate accounts with the containers with ease.

I hope this add-on can filter by wildcard, e.g. url like *.google.com.

This feature is sooo useful, especially with sites where you have multiple accounts. Or you don't want one site to leak to another! Or you visit, no soo safe for work sites!

This add-on is nearly essential. It safeguards my privacy, and it also keeps me organized. It's one of the first add-ons I download whenever I install firefox anywhere.

Handy for banking, keeping pesky trackers at bay, and using multiple twitter accounts.

Bueno, pero me gustaría poder enlazar los contenedores con los marcadores.

useless since it cannot sync accross multiple computers...
also it is not possible to define standards (eg. amazon.de --> always "shopping", etc.)

Love it.

This is so useful to me. It allows me to separate my personal life and school life. One time, I showed a Youtube video through Gmail at a meeting. Afterwards, a bunch of anime girls showed up in the recommended tile thing afterwards (it was because I listened to a lot of nightcore at the time, but it was still embarrassing). If you ever worry about something weird showing up on your computer during a presentation, or really any time you have to share your screen, use containers!

It's really helpful for signing into multiple accounts (for example, I have 4 Gmail accounts for school, work, personal means, and an organisation I help run. I don't want to be signed into my organisation's email all the time; I share it with 3 other people, and I'm only temporarily in charge of it. I don't want to have it hanging around, signed in all the time).

Génial pour laisser FB hors de ma navigation normale tout en le consultant régulièrement. Aussi, c'est parfait pour ouvrir plusieurs comptes du même média social en même temps. J'adore.

Nutzlos, da erstellte Container und automatische Regeln nicht mit über Firefox Sync abgeglichen werden. Auf jedem gerät die Container neu einzurichten ist dann auch nicht mehr einfacher, als mehrere Profile zu erstellen.

Just installed. Looks great as it exactly serves my need. And it shouldn't be too taxing on the CPU either! May be Firefox should add this as a native feature instead of an add-on, in future.

Edit: Would be awesome if you could add a way to rearrange the containers.

I love this extension! The only thing that seems to be buggy is when you click "Always open in ..." the toggle doesn't change, so it can be a bit confusing to know whether that setting is zeroed in.
