If firefox shows following error:
<pre>
This site uses an invalid security certificate.
The certificate is not trusted because it is self signed.
(Error code: sec_error_untrusted_issuer)
</pre>
without giving an option for creating exception then use following steps to solve the problem:

#Open preferences
#Go to Advanced -> Certificates -> View certificates
#Got to Servers 
#Click Add Exception
#Search for the site that is not opening and view its certificate.  In details tab look at value for 'Issuer'
#Add permanent exception for the certificate
#Now go to Authorities tab (Next to servers) tab
#Go to the issuer which issued previous self-signed certificate and edit trust for that issuer to identify websites.
#Close all settings / preferences dialog boxes and try to open site again
