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

Can't belive i haven't installed this earlier

good keep up

très bon module, mais quelques bugs. Il faut prendre un peu de temps pour bien le régler une fois qu'on l'a pris en main.
Le dernier soucis rencontrer c'est une page qui s'obstine à s'ouvrir dans un container A (car configuré par défaut pour celui ci) alors que j'ai manuellement et exceptionnellement sélectionné un container B

no wildcard,no manual edit feature，looping on onedrive.live.com and login.live.com

please add feature to open the same webpage in all container at once

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!

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