Excellent. Thanks Mozilla Firefox !

Can you add an icon before the line "Firefox Multi Account Containers" at the top, otherwise the entire interface will be very uncoordinated

ad tracking generally gotten worse (which generally is a good sign) after I adopted some measures: tab containers, firefox relay, ad block ultimate, fastfoward and jslibcache. Thank god to all these privacy enhancing technologies!

Foundational to how I use the web now. Augmented with the Smart Containers extension my sessions stay separated with a minimum of fuss.

We need this functionality on Android!

A useful extension to have multiple accounts in one profile and having option to limit sites only to a container is good for privacy. Hope sync with Firefox account better with time, right now some tabs forget what containers they were in during new install.
