Users who install fresh installations of AVG will not have a problem and existing users need to wait for VPS definition version 19061402 to be downloaded by their AVG software./

The good news is that the passwords are still safe and sound in the file and AVG has created a fix to include Mozilla's new certificate in their program. As Mozilla had issued a new certificate on and signed Firefox 67.0.2 with it, but AVG had not included it in the AVG Password Protection program, the Firefox processes were being blocked.Īs Firefox was not able to read the logins.json, the browser thought it was corrupt and renamed it to .

In a Mozilla bug post about this issue, Lukáš Rypáček, an engineering director at Avast, explained that the AVG Password Protection program will block a process' access to saved logins unless the process is signed by a known and valid Firefox certificate.

It turns out that this issue was only affecting users who had installed the AVG Password Protection feature and it was doing too good of a job protecting Firefox passwords.
