Completely Disable "Untrusted Connection" dialog

Posted

I am a professional developer stuck behind a proxy at work. The behavior of that proxy causes SSL connection attempts to retrieve a cert signed by my company, not the web site I attempt to connect to. I have no control over the proxy, so changing this behavior is out of the question.

I need to use Firefox for a number of things and am usually fine adding exceptions for sites I want to connect to. However, certain sites like github.com load resources from many other domains over SSL (CDN, Google Analytics, Gravatar, etc). For those sites I attempt to add exceptions to allow the company-signed cert, but I can only add them for github.com, not all the other sites, so even after adding an exception I am brought right back to the "This Connection is Untrusted" page. No matter how many times I try to grant an exception I never actually get to github.com.

Other browsers on my system are remotely administered and appear to be configured to automatically trust our company signed certs. I need to know how to manually configure Firefox to always trust these certs OR never ever show me the Untrusted Connection dialog and just maybe show red in the address bar when it doesn't trust the site's cert.

Apparently in OS X there are system level Certificate Authorities. I'm not sure why Firefox doesn't use these, but I was able to export the company CA and import it into Firefox. Finally resolved my issue.
