After a reinstall of Firefox (I had removed Firefox public and it disabled my Firefox ESR and Nightly both), almost all https sites are blocked off by Avast. If I disable https scanning, there is no problem. If I add an exception, pages in that domain work correctly.

With scanning enabled, I get SEC_ERROR_UNKNOWN_ISSUER on almost every https site, including even Mozilla's own site. The message says that the sites have been configured incorrectly. Really? The problem is within Avast's Web Shield behavior, not every bloody https site.

I'd like to use secure scanning, but not if I have to add an exception in Avast for almost every site I go to one by one.
