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.

Not a flawless, but setup when you have different Google accounts on different sites seems possible and works.
Does have separate one specific container cleanup button out of the box, which is the very point of this extension.

this is excellent addin no browser has this feaure

Absolutely excellent and huge quality of life tweak when needing to manage different accounts. Please add this for Android Firefox as well!

Excellent add-on, essential for my work!
