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.

Just what i needed. Thanks to this add-on i could uninstall Firefox Stable and stay only with Firefox Developer Edition, with the same functionalities of multiple accounts, only 1 web browser and until now, at least, no problems to report. Maybe the system to have to use middle button click to open a tab with the profile of the tab that you actually are, is a little "annoying", but really, i would love that Firefox Stable has this add-on built-in, like Firefox Nightly has.

Awesome
!!!!!!!!!!!!!!!!!!

通篇的废话，不知道说一下怎么把标签分类操作写一下，对比chrome的插件，火狐插件就是屎！

funciona a la perfeccion

Would have been perfect if you can sync settings

Amazing addon. Please add a possibility to choose container using right click in bookmarks

Helpful, but would love new tabs to either automatically select a container or give the option to select a container.

I love it... incredible

This lets me compartmentalize my browsing. I can sandbox different domains so that data isn't shared between them. This feature should have been built into all browsers long ago. Given the currently weak state of online privacy, it's refreshing to use a browser and add-ons built by a company that cares. This add-on is simple to use, but I think it would be a little more intuitive if all actions were available through the drop-down accessed by clicking on the Multi-Account Containers icon. In any case, this will forever be a default add-on for me in all new Firefox installations.
