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.

Incredibly simple and powerful. I use containers to isolate google and facebook, and it was very easy to set up.

Simple and intuitive solution to sound data management. Yet again showing us how Mozilla is committed to data privacy and an internet based on the users as the customer, not the product. Thank you.

I love this add-on. One of my go to whenever I bootup a new computer. Something to improve could be:
- Save configurations somewhere so its linked to my account. I have to manually add the same configuration over and over again when I configure a new computer.

c'est cool

Outstanding extension - HIGHLY recommended. Isolate your browsing correctly and efficiently and enhance your capabilities of containerization. This is a must have app. They recently upgraded it to include preference sync!

So useful, now I just need a keyboard shortcut to open new container tabs!

It's fantastic but the fact that the setup of Containers (names and assigned websites) does not sync between accounts is a huge drawback!

pretty useful
