how to fix insecure connection for every website

more options

Firefox will not allow me to go to any Websites. Any website I try to go to it tells me that it is an Insecure Connection. In advanced it will not allow me to add the website to exceptions. I have already uninstalled and reinstalled firefox and it did not fix the problem. Some examples of websites I am unable to go to are Google, Facebook, and Yahoo. the only Website I am able to get to is Bing and the Firefox website.
