copy (MAC) container associations to another machine

Firefox Installation and updates

I have most of Firefox on a new (Windows 10) machine just like it was on my old one, and it works and feels nearly alike. But I can't find where sites are associated with their containers. I would like to copy the file(s) where these are stored to my profile on the new machine. But which file(s)?

I should add that I already copied the JSON file where containers live (so all my containers show up on the new machine, but the sites don't open in the assigned containers).

Thanks for your help!
