Is it just your home page that is having that problem? Or is it all pages on Firefox?

If it is on all pages, This can be caused by a firewall blocking internet access to Firefox. See Configure firewalls so that Firefox can access the Internet. That link has a list of popular firewalls and how to configure them to work with Firefox.

Also see Firefox can't load websites but other browsers can

Does Internet Explorer not work? If so, see Firefox and other browsers can't load websites
