Type about:preferences#security<enter> in the address bar. Look under Logins,

Note: For Firefox v56+ its; about:preferences#privacy Look under Forms & Passwords +++++++++++++++++++++++++++++++ Turn on Remember Logins. To check the passwords you have listed, press Saved Logins.

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.

My Firefox account password is not listed in the saved logins list. Since it isn't stored there, I bet that if I log out from here and then proceed to log in, it will ask me for my password, resulting me being locked out of everything and losing everything. In the attached pic, changing the pass will delete everything, something I do not want to happen.

I ask about this for preventative reasons in the event of me being accidentally logged out of my firefox account on every device. I guess since there is no way to look at my firefox account password (registry entries, profile folder, etc), I will await for that moment to occur and manually restore bookmarks, history, saved logins and the rest.

In the Password Manager, look for: chrome://FirefoxAccounts . . . .

There is nothing saved in Firefox Lockwise or Password Manager related to firefox accounts and their credentials. I never used chrome either, so I don't have anything synced outside firefox. I may have pressed "don't save" when I entered my credentials and setting it to always automatically log in, thus never saving the login.

EDIT: After multiple tries I managed to type in the correct password. Consider this question solved. For anyone out there having forgotten your Sync Pass and not having it saved, you're out of luck. Always save your Firefox Account password since with it you can manage all other passwords and data.

The chrome://FirefoxAccounts entry in the logins.json file stores the Firefox Sync account authentication data (kA and kB) in JSON format. This entry is hidden from Lockwise, so you need to check logins.json.

Note that you can see this hidden chrome://FirefoxAccounts JSON data in an exported CSV file.

Login data you use to manually login via https://accounts.firefox.com/signin should be visible in Lockwise.
