Firefox 3 and Revoked SSL Certificates

Today I discovered that Firefox 3 will refuse to display a site over HTTPS if its SSL certificate is revoked. And even though I am not questioning merits of this decision, I still would have preferred to have this behavior configurable, either somewhere deep in Preferences or at least via about:config (quick scan of the latter did not result in anything useful - did I overlook it?)

Same deal here, check out for an example.

I like the other warning, where if its untrusted you can add the exception, but completely stopping you?

@dave - looks like Nokia fixed that site already.

Found this blog whilst experiencing the same problem. I also found a solution (although I don't know the impact on security). It's something to do with OCSP. If you go to Preferences/Options > Security > Advanced > Encryption > Validation and uncheck OCSP.

I found this solution at the following site. . .
