Today I have been getting a lot of "This Site Is Untrusted" notices for sites I have always used. Also today on Youtube I get "An error occurred please try again later" notice each time I try to play a video and instead of there being pictures for each video there is the word "Thumbnail". When I use Internet Explorer I have no problems playing Youtube videos and there is a picture for all the videos displayed. But each time I try to navigate to another site with IE I get the message "There is a problem with this website's security certificate". My operating system is XP Home and I use Firefox as a browser. I made several typos in the topic title because I was tired when posting this. How do I edit the title? Thanks for any replies.
