Is it possible to assign site into a container, while keeping current session cookie?

Now you need to re-login (once) inside the container, which is.. only mildly inconvenient 😅

I like the extension, but the user interface is insanely unintuitive and there are no instructions in the add-on's page. So you will have to spend a lot of time to figure out how to use this add-on. You can find some documentation by googling and some third party reviews that give even more insights on the benefits and use cases for this. I don't know why Mozilla makes it so difficult to get started with this add-on by not connecting it with meaningful documentation.

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

Only thing that's missing is the ability to edit containers in large quantities. I'm using it in conjunction with Temporary Containers and it'd be great if I could delete or edit em en masse...

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.
