It does what it says it does. It would be nice to have a per-container proxy settings, though.

A great must-have extension.

Not a 5-star since Sync across devices just don't exist. Will update when it does.

My golly this extension is giving me a headache. You see, I am trying my best to limit how many browsers I use to just one -- Chrome I believe purposely makes G Suite programs work better on Chrome (GMail, GDocs, etc.), while Edge has a very fast and sleek PDF reader, but Firefox... has THIS!!

This multi-account container is SO GOOD that it is the one thing that neither Chrome nor Edge have anything close to. For background, I have my personal account (for my social media, bills), a school account (assignments, documents, etc.), a junk account (i.e. for registering to a free anime streaming website), and lastly my business account which also gets busy. I used to lose my MIND having to sign in and out in different websites (E-mail, Office.com, Instagram, Twitter) or use an incognito mode, but this saves me SO MUCH TIME, and reduces the confusion I used to face, trying to remember different passwords or which account I am supposed to be using.

Thank you Mozilla. This app single-handedly makes Firefox a mainstay as one of my favorite browsers.

multiple google and office 360 accounts open at one - solved!

This is very handy when using multiple O365 accounts. Love it.
