Out of the blue Firefox will block Google (my home page) and display a security page stating "This Connection is Untrusted You have asked Firefox to connect securely to www.google.com, but we can't confirm that your connection is secure...." After confirming the exception for Google I am presented with "Invalid URL" Idiots on the wed concerning this issue always say the same thing as if no one has ever thought to clear the cache, delete the history, and restart Firefox; there has to be some other reason this keeps happening. Sometimes I give up an leave the computer because I cannot access Google. The screen shot will not upload so if you would like to see them provide an email address and I will send them. Francis
