Hi frankzappa, thank you for sharing the certificate Firefox doesn't trust. It was "issued" (signed) using this information:

AVG Web/Mail Shield Root generated by AVG Antivirus for SSL/TLS scanning

Did you just install, update, or Refresh Firefox? Or update AVG?

When you first install Firefox (or Refresh it), it doesn't trust fake website certificates generated by "man in the middle" software. So you need to create trust between Firefox and AVG.

There may be a way to trigger AVG to inject it's credentials into the Firefox certificate file somewhere in AVG's settings, or you may just need to restart your system and let AVG discover that you now have Firefox installed.

This article has more background on this issue: How to troubleshoot security error codes on secure websites.
