Marvelous extension to separate your day-to-day login data. I use it for web development and social media management.

I absolutely love this add-on. Instead of using multiple browsers to separate work and personal, I can now use tabs in the same browser. Designating containers for individual websites is also a great feature (looking at you, Facebook).

Assuming this add-on works the way it seems to I'm very impressed. The only issue I'm having is not being able to re-sort containers in the list.
See this github issue:

The best Browser even better with this extension ! Good Job !

Thank you for update to support sync. I hope it will be very useful now.

humanaty's only enemy is the state & the Centrol bank

Good

Love this! I can force site to open in container. And I feel safe

Very helpful extension. I use it every day at work. Keep a good work :)

Very nice extension. Should be included into firefox by default

Great idea with a nice implementation!

I hope that it will be possible to change the container of a tab without creating a new tab (and then having to delete the old one).

Multi-Account Containers were one of the main reasons I came back to Firefox (along with Lockwise and the awesome new Firefox for Android!)

I love using this extension to be able to easily switch between work and personal accounts on the same computer. Recommend!
