How do I make an unsecure website secure so I can use it?

more options

I'm trying to use a website that I've used literally thousands of times and now firefox won't open it because the website doesn't have a secure certificate. I can't find anything to override it and I'm completely out of options now.

Can you post a link to to this website?

Note that there can be problems with revoked certificates that can be caused by the server implementing a fixup for the heartbleed vulnerability.

You can temporarly set the security.ssl.enable_ocsp_stapling pref to false on the about:config page to disable OCSP Stapling.

Make sure to check in a few days if you still need this workaround and if necessary reset the pref to true.
