Server Certificate Exceptions are not retained by Firefox 103
As the subject says, certificate exceptions added "permanently" in the Certificate Manager are dumped at various intervals. For example after updating to 113.02, my certificates for a local router and switch were gone. Sometimes the certificate exceptions seem to be removed at random intervals. Can't really nail down what causes this but the "permanent exception" is not honored. I added several certificates a few days ago, now they're gone.
This has been an ongoing PITA for the past year or more. Why does Firefox make this so difficult?
