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.

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!

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?

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!

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.

This is an excellent way to limit tracking data pollination across web services. You can use your cloud mail at home and at work simultaneously and without fiddling with profiles. You can shop in the Shopping container and not have the items you looked at populate the ads you see on other websites afterwards. You can run a casual news browsing session in a dedicated container and not let various websites you visit correlate too much about you, or the web giants that track your account's activity learn that you were really into that Taylor Swift story ;)

Awesome !
