Error is "sec_error_unknown_issuer", regardless of deleting either cert8.db, or cert_override.txt, resetting FF, or anything, I can't ADD Exception, Works in IE
I get this from the server that runs the WatchGuard SPAM Filter, and I USED to be able to add an exception, and it was fine.
Under "Technical Details" I get:
"An error occurred during a connection to sp-servername.domain.local:4119.
Peer's Certificate issuer is not recognized.
(Error code: sec_error_unknown_issuer)"
Clicking the "Add Exception" Button does NOTHING...
I can take the URL, copy/paste it into IE, and it works fine... It's happening on multiple systems... All Windows 7 All FF Version 37.0.1
