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 The page has a security certificate that is outdated.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).
