I've been using this addon for a while and it has been great! The last 3 weeks it has been asking me which container I want to open Youtube each frickin' time I visit Youtube. I haven't found a solution to this, so this lead me to uninstall the addon.

I'm going to lower my rating even though I still think this add-on is crucial and fantastic. But the fact that you still, after many years, haven't added the option to manually add a url to always open in a certain container is ridiculous. You should know how chaotic and irratic the devs of Google and Microsoft are today using 20 different domains just to be able to sign in somewhere. It's like they all suffer from DID. It's a hassle to use containers because of this, since you so often are thrown out of the container. Fix it!

Хочется верить, что все именно так, как заявлено в описании. Good

very interesting and usefull tool! Thanks!

Works good.
But would be nice if you could add password protection (or encryption) for containers.

Does not work reliably for me at all. After a Firefox restart, tabs will randomly become unassigned from their containers, and occasionally the entire contents of a container will disappear. Then I am left with trying to sort out the mess of tabs left over, attempting to put them back inside containers. Happens on multiple machines and multiple user accounts, perhaps some incompatibility with uBlock Origin? Or this addon is just not mature enough yet.

This plugin is the reason I switched from Chrome. It's awesome that it keeps things self contained. The only thing I would add is a way to hide containers from the drop down list. I have one for Amazon that always opens in it's container. It would be great to not have that on the list because unless it's amazon.com I don't use that container.

I just can't figure out how to always open a site without a container. "Remember my decision for this site" seems only works for containers, not no container.
