one extension to rule them all. serve my multi-browser needs.

Can't belive i haven't installed this earlier

good keep up

Excellente! Most people here are praising MAC for its features, and they're right.
There is one review below by squarrell who finds he has trouble with the extension, but there IS a solution.
I've found that looking for the particular MAC tab for a particular account is irritating. The popup as you hover across the tabs is slow, and you have to run across them until you find the one you want. Better is to use MACs with the Simple Tab Groups extension. STG names them in its vertical dropdown, easy to inspect, and MAC puts an annunciator in the address field. An unintended method, but it works.
All hail Extensions!

FurryFox ❤️❤️❤️

This is now one of my must-have add-ons!

I am so happy to find this extension and switched to firefox for it. it really helps me with aws accounts.

Perfect for keeping youtube accounts and stuff like that separated by tab.
