great for using different environments, accounts, projects, etc!

I really like the idea of container tabs and I want it to work. I prefer to have certain sites quarantined and the ability to have multiple logins on the same website. The ergonomics of getting that to work are what bothers me. e.g. setting a site to always open in a container tab will still prompt the user if that's what they want. There's also some issues involved in using Oauth2 across containers.

I thought at first I would use this to contain my work related activities and keep them away from everything else, but I now know that separate profiles is the answer to this use case.

All in all I think this is a valuable feature and I look forward to it getting improved upon in the future.

Awesome add-on.

Ugh! Broken again since last VPN update. It no longer recognizes active Mozilla VPN subscription and instead prompts you to "Get Mozilla VPN" even though you already have it.

amazing

While the containers are really useful, the user experience is lacking.
For example the sort button has no confirmation. I clicked by mistake and all my tabs are now sorted by some weird logic and not by my context. And I cannot revert this.
