I needed a method to allow me to run multiple WhatsApp messaging shells from different accounts at the same time on my Desktop/Laptop computers. Firefox's Multi-Account Containers Extension allows me to do just that. Seems to work perfectly.

Great extension, top for unblocking specific sites with custom proxy settings (instead of using global VPN). Bravo, Firefox, spread the word!

This add-on is what differentiates Mozilla Firefox from the rest.

Incredibly useful! It turns Firefox into 10 browsers in one, learning your preferences so each aspect of your life stays organized and separate!

Amazing. No need for different windows, different sessions are tied to specific tabs with color-coding. Much better solution than in chromium where you need a whole window

Lifesaver for some usecases. like mine :)

Absolutely irreplaceable and mandatory for me

Solves all issues I had with bare containers implementation.

nicely done!

Love the addon. Only thing missing for me is the option to sort all containers alphabetically.

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.
