I decided to use Firefox for real these days and really learn about its features. This extension particularly is a selling point for me. I told my girlfriend about it and she was impressed about how it improves workflow and how Chrome has nothing even similar because their addon SDK simply doesn't allow it. I am impressed too

"Multi-Account Containers" has improved my workflow, making me more efficient. By being able to keep my cookies and histories isolated based on activity/website, I don't have to open a private window every time I wish to look at Gmail or use a Google search service like Google Scholar. The ability to specify for a website to automatically open in a chosen container is an excellent additional touch that facilitates the process even more. Finally, it also works well in conjunction with my tab group extension ("Simple Tab Groups") -- I have been using both for several weeks with zero conflicts or other issues on either a Mac or Ubuntu 18.

I love the app EXCEPT I cant put the list into my own order. To do that I have to uninstall it, then reinstall it, and enter my containers in the order I want them to show up in. To do this every time I create a new container is a royal pain in the @@S. FIX THIS ISSUE!!!

Would love an option to reorder containers!!

This add on does exactly what it is supposed to do. Perfect! I can use Google services, Facebook, Twitter, and others all in separate containers.

As I manage personal, work, and educational Office365 accounts, this extension is essential to efficiently manage my online life.

A good feature which can be made better: 1) Sync opened tabs in different container across devices. 2) Send a normal tab to a container and close the original tab (currently it reopens in a new one in the designated container and so you result in having 2 tabs). 3) Make hiding a container easier (e.g. by right-clicking on the tab and have a option in that menu; currently users have to click on the add-on icon, click the tiny arrow of that container, and then click hide).

Not user-friendly despite not looking very nice. I tried selecting "alway open this site in..." "private" for addons.mozilla.org. I don't know what I am doing wrong but when I go to addons.mozilla.org it doesn't switch container. If I can't rely on this than it is useless ;(. But I love the idea (right now I am using multiple browsers)!
