Now when I do a Firefox Search (whether Google, Yahoo, etc), I get a "Invalid Security Code" / "Issuer Certificate is unknown" error message train. I can't understand why these sites would produce this result but am afraid to override the error message worrying about some kind of malware interference problem.

hello, a possible solution depends on different factors:

  • what is the error code shown under technical details on the error page?

in case the error code equals sec_error_unknown_issuer, please attempt to add an exception on the bottom of the error page (don't add it for real though) & inspect the certificate like shown in the screenshot

  • which issuer information does the certificate contain?

please report back with this information. thank you!

Hello Philipp, I did a Firefox restore, then reinstalled apps/etc and for whatever reason, the problem resolved itself. I am saving your reply in case the issue comes up again. Thanks for taking the time to help. Brent T.
