Containers are by far one of Firefox's best features. They're easy to use, reduces hassle, protects against Facebook tracking and helps organise tabs for website with multiple logins.

The only issue I have is the colors on top of each container tab, it throws me off and I would really appreciate the option to remove them or have them be on the side of each tab instead of the top.

Its the most useful and most unique feature from other browsers, I maintain my work, education and personal profiles so effortlessly with the containers

Containers save a ton of time when I'm dealing with several accounts for the same systems. Isolating Facebook from search is precious.

Ideal add-on if you have to manage - for example - multiple AWS accounts at the same time.
