When I try to hit google.com, I get the "Your connection is not secure," then under Advanced, get this:

www.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. (Error code: sec_error_unknown_issuer)

The certificate itself is issued by Websense Inc.

I have tried removing the cert8.db file, I've tried adding an exception. Nothing working.

Thanks

Got it. Basically, I had to export the signing certificate from Chrome (where it was working) and import from within Firefox, and I'm back in business.

Thanks.

If you have the option to set Websense not to intercept/filter secure connections, you could try that. It may depend on whether it's a personal Websense product or a company/enterprise product.

To make Firefox compatible with Websense filtering -- if tests with other secure sites confirm the same issuer and you trust this software -- you probably need to import the software's or proxy's signing certificate into Firefox's Certificate Manager on the Authorities tab. This thread has an example of how you could do that:
