Containers has allowed me to completely give up Chrome. I like the functionality, and it is intuitive enough that I will keep using it. Please install to keep Firefox going!

Very good

The best! thank you

great idea, but it breaks ctrl-shift-t functionality a lot of the time. also would be nice to select active add-ons per container.

Really good, does the job pretty well, cannot see myself without this extension ever again.

I would really like if theycould add the ability to add websites to a container directly via the extension icon.

It's really great, but I wish the settings I have for each container were ported over with Firefox sync. The containers, settings for each container, etc. I understand this request may have difficulties I don't understand, but this problem is the only thing stopping me from rating this add on as perfect.

Great to split my work identity from personal identity. Great to simultaneously use the same site using two accounts.

Awesome for Multi-Account Task!

A recent update seems to have caused CPU usage to go out of control with this extension enabled. I've disabled the extension, and noticed I still have Container tabs functionality, albeit without the extension toolbar button - so I question the need for this extension.

Container tabs have quickly become a must-have feature for me. I have quite a few sites where I actively use multiple accounts (Google, Microsoft, Amazon) and not having to use a separate browser with a completely separate profile and set of addons is great. Even with sites that do allow simultaneous sign-in with different accounts, opening, for example, a work-related link in my work container ensures that it will use my work Google and Microsoft accounts and not accidentally leak/link any personal data.

Does the job very well. Imo it should open the contextual menu allowing to select the kind of container on a right click instead of the long left click.

Nice

love it, does what it says without any hassle.

Killer feature. I switched to Firefox just because of that functionality.

Me va genial con esta extension logro manterner todo mas admistrado, evitando regar toda mi informacion de un lado para el otro, tambien es muy util la opcion de ocultar y desplegar pestañas, ya que soy el tipo de persona que abre un monton a la vez y con solo un click las puedo ocultar inmediatamente y ponerme en otra cosa

This app is what downloading.

Really useful extension for keeping social networks ever reaching tentacles out of everyday browsing data.

Containers causes some issues with other macOS 10.14 Mojave add-ons like Reddit Enhancement Suite. This issue was not present in High Sierra.

I say Firefox Account Containers are excellent as they give u another layer of security and in today's world we all need as much security as we can get.

Generally, a great concept that changed the way I browse the web.
It could do with some usability and integration refinements but development is active as of summer 2018.
