De ideale manier om met meerdere accounts en een domein te werken zonder van profiel te hoeven wisselen.

This extension is 100% what's keeping me on firefox

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.

It's a must-have add-on if you care about your privacy. Intuitive, easy to use and absolutely customizable. I love it! A WARNING FOR MACOS USERS: Keyboard shortcuts ⌘⇧[3 to 5] are already taken by the OS (macOS screenshot shortcuts). But if you switch them in Add-ons Manager > click the gear > Manage Extension Shortcuts to ⌥⌘[number] it works just fine.

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.
