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

Love it.

works as advertised

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.

Simply Awesome

I love this! It saves me from opening multiple windows and struggling to find the one I wanted!

WIsh it has Sync functionality . I have to add my bookmark again in personal PC

I really like this but the biggest problem is that it doesnt save the tabs if I restart firefox.

This is the best! Protecting my privacy has become a much simpler job with containers. May I suggest a tweak to enable us to choose more colours and icons?

Its Good, it helps me open my personal and professional gmail accounts in parallel in separate container without sign out or losing the session.

Perfect for school accounts and other similar situations. Like private mode but more convenient.

I love using this to organize my time between Work and Family sites

I really like the idea of this. The implementation is pretty solid too!

Funcional, porém faltam algumas funções para facilitar seu uso.

Practical and easy to use!

Really useful!!!

As someone who has given away using Google products but unfortunately has to use G Suite Apps in the workplace, this is a godsend.
