Firefox experienced a glitch while I was using Fanfiction.net, after restarting Firefox I started getting: An error occurred during a connection to www.fanfiction.net. Invalid OCSP signing certificate in OCSP response. (Error code: sec_error_ocsp_invalid_signing_cert) every time I tried to visit the site. I've used http://www.downforeveryoneorjustme.com and the site is up for everyone else. I've even tried a suggestion from other similar problems and temporarily disabled strict OCSP checking. It didn't work. I can still access the site using IE but that is a very unsatisfactory solution. Any help would be appreciated.
