When I try to connect to yahoo, I get the following message: The owner of www.yahoo.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.

When I try to connect to mozilla, I get the following message: The owner of www.mozilla.org has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

Does anybody have a solution? IE works just fine, btw  ;)
