The identity of this web site or the integrity of this connection cannot be verified Popups appears many times and can be eliminated by clicking X (close) on the message. Usually about 10-20 of these appear behind the browser page. I do not see the message until I close the browser. I have tried every suggestion from many sources and can not rid the problem. One suggestion was to change the wording on Firefox Certificate Manager deleting BUILTIN OBJECT TOKEN. I can not find access to try this method. I have tried to delete certificates that look suspicious and they reload when you open the Fire Fox Browser. All of the certificate popups are from sites I do not visit. Image attached. Any help is much appreciated, Todd
