Hi Mike, I'm assuming you don't want everything to mingle together, you want the data from the accounts to stay separate?

Firefox stores your data locally in a profile folder under your Windows user. So each different Windows login should automatically have a different profile folder, and if you log each of those Firefox profiles into a different Firefox Account, everything should stay separated.

If you log in under a shared Windows account, it's still possible to set up separate Firefox profiles, but you'll have to more actively manage which one you're using, and also make sure not to switch the profile between different Firefox Accounts or you'll probably end up mixing all the data together.

Am I getting the gist of what you're looking for? If not, could you provide more information on why you want to connect to different Firefox Accounts?
