Just automatically works, without having to set anything up! Saves me from setting up a Google container and telling the Firefox Containers add-on to "Always open this in site in..." for every different Google domain, on every new PC I use.

NB: I don't use Google to sign into anything, which is a big reason why this extension "just works" for me. If you use Google to sign into certain sites, this extension will cause you trouble, by design. --I use a password manager (BitWarden) to sign into all of my accounts (both so I don't have to be signed into Google everywhere, but also so I don't have to remember whether I signed up with Google/Facebook, which email, etc...)

This was working really good

Works great!

stil loving this container :) but would it be possible in the options, to choose a color for tabs that are in containers ? ( now it is red, i would like it a different color , mor in keeping with my firefox theme lol ) Still great container :)

Excellent, Consider it critical to any Firefox install!
The only thing I would add would be the ability to separate the Google container into separate containers again, This way you could isolate Google services from each other, for example YouTube from Google search
I no that the option to ignore selected Google services is available but I would prefer to still contain said service from the rest of my browser.

Thank You containers-everywhere , Love you long time!!

Super!
