Works well for seperating my tracked internet history, without needing to setup a second Firefox Profile & Mozilla Account. This in addition to the Facebook, Google & Twitter Containers help keep those 3 from tying everywhere I go on the 'net to my accounts.

this is the god extension for me. my life saver please continue. dont stop ever. i love you firefox

This is very powerful tool for productivity. I shifted from Chrome to Firefox a week ago.

Must have extension for every developer.

It is a must have extension. I primary use it during development where I need different states of cookies and logins.

The only thing I'm missing is to be able to open a URL in a specific container e.g. by specifying a protocol prefix in a href (or whatever data-x-target="{container name}").
I can not assign a full domain as I need to view the same domain in different configurations, but I'd like to access them by just clicking on my "bookmark" link - My site (Beta-2), My site (Alpha).. etc...

I only wish that we could assign an entire bookmarks folder to open in a specific container. Love it and a must have extension.

One of the most useful extensions if you are concerned about your privacy

Ottima. Ha qualche problema con alcuni siti.. Ad esempio GitHub. Se assegno il contenitore a GitHub e poi apro codespace in un repository si crea un loop strano e non riesco ad usare codespace..

Makes my browsing life great again.
