Fantastic app to keep separated profiles. It takes sometime to sort out with site in in which container, but afterwords, it's great.

Love the feature, I like having multiple accounts setup in different containers, keeping work/private separate.
And it's great for testing as different users when developing code.

Mozilla didn't merge https://github.com/mozilla/multi-account-containers/pull/1500

Absolutely essential if you want to be more organised and/or more secure.

This is an absolute lifesaver. Too many MS365 accounts in my life for any sane person, but being able to keep them in separate containers holds the insanity at bay a little bit longer. Keep Facebook isolated in its own nosey portion of my browser, too, which is a nice out-of-the-box option.

This functionality is amazing and I need it on a daily basis. My dream though is still to have these as separate browsers in my dock/taskbar with smart url functionality to open certain urls in certain containers and/or ask me which container to use.

Works great, and separates my "work from home" stuff from personal. My work automatically tracks my searches whenever I am logged into their MS services (which includes onedrive), so this means I can juggle multiple personal and work tabs and not have to worry about leaking info. Made me switch to Firefox as my primary browser on desktop.

Great extension. I have a couple of request.
-Can there be a way to manually type the domains I want in "x" container? Like by pressing in the "Manage Site List" just type the domains I want in there. I'm having issues where several redirects prevents me from adding exactly the URL that I want.
-Also to just be able to decide to add a webpage to specific container from a bookmark without actually opening the web page in the container.
-And more colors and symbols options, as there's no many.
