Screenshot from phone, but same warning message when i do it on my computer.
I have my bookmarks, history, etc. saved on my computer (in the firefox profile folder). But i'm afraid firefox may delete my data once i reset my password. If not, will firefox sync my local data to their cloud after pw reset?
Are you just changing the password or have forgotten it and need to reset it? If it’s the latter I’m guessing you can’t reset without losing these things; basically you’re losing the encryption key.
