In the past 2 days I was receiving an error code when I tried to open Firefox, telling me it was an only good til 9/24/2011 and the date was 9/25/2011. The error code was: error code: sec_expired_certificate.
Secure connection failed...xml.freecause.com:443 invalid
Secure connection failed...xml.freecause.com:443 invalid

Try a different home page. The page has a security certificate that is outdated.
The security certificate for the xml.freecause.com domain has expired because it was not renewed in time.
You most likely have an extension that tries to contact that server and you will have to disable that extension until the site has renewed its certificate.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
