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 :( .

If you use sync, ALL selected data would be merged with all members of the sync.

You have two options.

1) Create a new sync but sync only login data.

2) Password:Recovery:Restore:Export +++++++++++++++++++++++++++++++++++++++++ (Win) PasswordFox v1.58 - Extract the usernames/passwords stored in Firefox Copyright (c) 2008 - 2017 Nir Sofer

In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.

Firefox stores the login information to connect to the Sync account as a hidden entry (i.e. not visible in Lockwise) in logins.json in the profile folder as "hostname: chrome://FirefoxAccounts".

EDIT: Note that you need to copy key4.db as well if you would copy files to another profile and copying this file will replace are currently saved logins, so you may want to keep a copy of logins.json and ket4.db or export existing logins in case you have special logins stored in a profile.
