User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-GB; rv:1.9) Gecko/2008051202 Firefox/3.0 Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-GB; rv:1.9) Gecko/2008051202 Firefox/3.0 When a https server is visited on localhost then FF will not allow a certificate exception to be added. If the same site is visited via 127.0.0.1 then things work as they should. I get the following alert message: Alert login.yahoo.com:443 uses an invalid security certificate. The certificate is not trusted because it is self signed. The certificate is only valid for <a id="cert_domain_link" title="PortSwigger">PortSwigger</a>. (Error code: sec_error_untrusted_issuer) Then I click ok and I am on a blank page rather than the exception creation error page. If I try to add an exception manually through the encryption tab in advanced I get the same error message when I click the "Get Certificate" followed by the "Unable to obtain identification status for the given site". Reproducible: Always Steps to Reproduce: 1. Set up a SSL webserver on the local machine with a self signed cert 2. Visit the site with https://localhost 3. Try again with https://127.0.0.1 to see correct response Actual Results: Get Alert error message then a blank page Expected Results: Get and invalid SSL cert error page with the ability to add an exception I have confirmed that this is not the case under windows and all works fine there. I have seen the same problem on another OSX machine but have not had chance to look at a linux build. Before managing to isolate the problem I reported this bug 437990 which is a symptom of the same problem
I would say it is probably a duplicate of bug 435558. Deanx does the problem goes away if you set network.dns.disableIPv6 to true? If so, it is definitively a duplicate of that one
I can confirm this solves the problem so is a duplicate of this bug. Sorry bout that my bad.
