This is the thing that keeps me using Firefox. I daily log into four Office 365 accounts: personal, business, client, charity. This feature is now indispensable to me.

I wanted something like this.
may be in future I'll see there will be an update to open a Tor tab in container, in a sec

Great extension, for splitting tasks and accounts between tabs. No problem so far on Arch. Too bad there is no shortcut (yet?) for creating a new tab inside the current tab's container (I recommend "New container tab" extension as workaround)

Excellent container... does a great job; user end config is the only cross site I have seen... Thanks a lot :)

Very usefull!!!

I like this addon. Must have for people who wants split personal and work accounts.
I could be good to have choose menu on already opened tab. At the moment UX not so friendly, I should open new container window and copy-paste url. :( Is this work already planned on roadmap?

Helps keep tabs and activity neatly separated.

Love it!

Isoliert Geschäftslogins und -tracking zuverlässig von Privataktivität. Die Bedienung ist denkbar einfach. Eine der besten Ideen von Mozilla seit langem; alle Seiten funktionieren nach wie vor zuverlässig. Vielen Dank für die Entwicklung!

Facilita muito a administração de várias contas

A nice way to isolate your intranet websites with potential sensitive information from your browsing the rest of the web within the same browser.

Awesome extension, I'd recommend to everyone.

Bien

Needs keyboard shortcuts for containers.

It saves me from opening Chrome.

good soft

Really great.

Even better if container preferences were synced between computers.

this addon is truly the finest.

i love him
