Logging into different accounts are merging information for everyone
I'm not sure if this is a question or not. But when I had a friend log out of my account on my PC Firefox browser and sign in to hers, it merged her personal data to my local PC and then merged with my own account after I logged into mine. There's an option to delete it, but if you accidentally don't check it, it stays there. She tried logging in and logging out and checking the delete local files, but her information is still stored on my PC and account. Funnily enough, later that day, I logged into her PC and browser and it's the same thing there. We only realized this just now. Is there a way to fix this all at once?
It'd be much preferable if Firefox accounts were instanced by default, and all personal data is exclusively with that account. With options to merge or download information longer term.

A profile isn't meant to be used with multiple Firefox Sync accounts because that will merge the data from both account, so the result is that both accounts have the personal data from each individual account. You should have had a warning when connecting the profile to a different Firefox Account.
You will have to cleanup this manually. For the bookmarks there are backups in the bookmarkbackups folder available that you can us to restore the bookmarks.
Best is to create a new profile in such a case.
Lordy lordy, this is incredibly poorly implemented. Profiles should be what the Sync Accounts are, no other browser or account system works like this.
Profiles need a front facing UI rather than being buried in the settings, and Firefox Sync should be an option in the settings.
