All of a sudden the latest version of Firefox is not opening up one of the better known "dating" sites whose 3-letter acronym starts with T, saying "because the authenticity of the received data could not be verified." How do I rectify this? Plus, in trying to see if Safari would work, the name of the site got stuck forever it seems in the autocomplete of its google search bar. How do I remove it? For the record, Safari didn't work with the T site either. Thanks for your help.
