''' I have like 100 Firefox profiles that i use for different topics and would love to sync them all at once, i was looking for a file that stored the login approved for my Firefox account info to just copy paste that one file in all of my Firefox profiles, but can't really find it. This is a problem because every single time i have to introduce my email and my password and sometimes it also asks for an email verification code :( .
