Hello, yesterday I format my PC and re-install all my software, also firefox. I put the credential but my account was locked for security reason. I don't receive any mail (I got a gmail). I read all tutorial to try to resolve the issues. I wait 24hours, but the issues persist. My phone is connected at the same account and work fine but from desktop is locked. I also try to log-in different browser (firefox and Firefox Nightly) but the issues persist. I also try to log-in in different PC but the issues persist. I also add accounts@firefox.com to my contact but the issues persist. I tried all the solutions but I couldn't solve the problem, please help me ,thanks
