I use Firefox with MACs and it's really awesome. I notice that the configurations for my containers and their settings is shared via my Firefox account, which is not a big deal, but results in an awkward situation for me.
I would like to set an "Always open in this container" for a certain site, but only on this particular device. To make this concrete, the situation is that I would like, on my work laptop, to always open Google Meet and associated pages in my work account container; but I would like that setting not to propagate to my other devices like my personal computer, where I also use Google Meet for personal calls.
