Just updated to FFx 57.0 the other day, restarted everything and now I can't find login.json or key3.json to restore my passwords. Please Help!
The thing that really pisses me off is that I just had everything yesterday. I just turn on my laptop this morning to do some schoolwork when it site asked me for my login. The thing is, I already had my username and password saved from before. Went to check my saved passwords and everything was gone. No big deal, just gotta pull it up from my "old FireFox data" folder, problem is login.json, where I got my passwords from last time I did this, isn't there.
See if have two profiles : https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
Please let us know if this solved your issue or if need further assistance.
I went through each article to see which one would help me best and went through the steps and all I got were the passwords that I just started adding, instead of my old passwords.
