I updated nearly all of my passwords on my desktop to firefox-generated passwords. Then I was on Firefox on android, and I needed to login to something, but it was filling in the old password. I pressed "sync" in the app, but that didn't update the password. Then I discovered that for reasons I don't understand, all the new passwords in firefox on my desktop had been overwritten by the old passwords from my phone. How do I recover my passwords? I'm locked out of everything.
