One of the most useful extensions I currently use. I do wish they would add tab stacking and tab previews, but all the same, 5 stars.

Finally, an easy way to have multiple logins into Office online on different domains!

And a complete separation between your private and tracked life!

The only thing that is missing, is the option to manually add a URL via copy & paste. Many services quickly redirect you after they find out that you are not logged in, and it can be tricky to catch them at the exact right time.

Excellente, made my life easier with multiple e-Mails and different projects open at the same time. Congratulations to Mozilla Firefox team again!

I'm A SERIOUS Multi-Tasker! FF Containers Allow Me To Work On Multiple Projects ALL @1 Time...Without Having To Log Out Of 1 eMail Just So I Can Open Another 4 Example, Just Open A New Container & Voila! Unlike Some Other Browsers - When U Open A New Container ALL The Add-Ons & Features Stay In Tact...No Multiple SetUps For Each New Account. There Are Add-On Containers To Secure Things Like Facebook Container, Etc But I Find That FF Containers Fulfill My Needs & W/Other Security Features Already Built-In To FF As Well As Add-Ons, I Feel GOOD, YAH!

Indispensable

I like this extension a lot.

"This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing."

But MOZILLA why have you removed it from the recommended extensions??

This really ought to be built in to the browser

This addon allows me to run google.com and youtube.com in a container such that I'm not logged in with my google-account. But at the same time I can open google drive, scholar, gmail in an other container and still be logged with my account. This is extremely convenient.
