Extremely useful. One improvement I suggest is that whenever a site not previously allocated to a container is opened, that it be forced into a non-container tab and NOT opened in the container that it was linked from.

Great add-on for privacy and containerizing your online life. Thank you, Mozilla!

Very useful when handling multiple customers.

Really good to stop cross-site tracking! Make containers, and even use different VPN for every TAB if u want too..

such a good tool for privacy!

amazing! works perfectly!

takes a second to get it, but once you get it you get it, never knew I needed tabs in a container before, good stuff

Very nice.
