Hello! i can't access both hotmail an facebook. I have cleared my cookies and caches but it didnt help! what should i do?

Do you get an error message page about the secure certificate, or a more general message that the page couldn't be loaded? Or does the page load but not work correctly? Not sure this is relevant, but just in case: Firefox 23 has a new feature to block "mixed content" in a page. This article describes how to spot that condition and address it: [[How does content that isn't secure affect my safety?]]
