Very useful for having multiple sign-ins on sites that don't support it well

I signed in to firefox just to leave this review. This app is heavenly! Thanks Mozillaa!!!!!!

Really great add-on to manage online lives

This is my most useful extension. It's saving me so many headaches.

Brilliant, even with 3rd party cookies on the way out this is still great for using multiple accounts on the same site. I use it isolate work and personal accounts and to isolate accounts for different clients at work.

Extension that I cannot live without.

Excellent and straightforward way to increase privacy.
