Coming from Chrome, where I used profiles to separate work browsing from personal browsing, I find this very useful.

I really like this add-on. It would be perfect if we had the option to 'lock-down' a container of choice, in the same way that Facebook Container is locked-down.

Works great, but sometimes I forget that when I log in on a Google account for a different website I need to open my separate tab.

Easy and straightforward way to keep different browser contexts separate.

Easy to use, Very effective. An essential add-on.

this works great

Extremely useful feature.

Very useful and simple to use. I think I like it better than Chrome's profile switching.

A must have. I've switched all of my multi-profile activity from Chromium (not my preferred browser) to Firefox (my preferred and favorite browser) Multi-Account Containers, finding it much more useful, handy and, especially, resource efficient. Keep it up, Mozilla!
