Hey, Your computer also appears to be running a proxy: eappprxy.dll and the crash was in an httpchannel. Is your proxy configured to allow the page you are visiting?

Also noticed fetchOcspHttpClientV1, wanted to check if you have ocsp on, this in on by default.

It was also a read access violation, does Firefox have system permissions to read the file that stores your stored certs?

Not sure if this is farfetched, but we are happy to help when you post back.
