Thank you for trying to help me, but many of the suggestions and explanations are dead ends because I cannot get them to work. I cannot get the latest version 95 of Firefox to update despite repeatedly trying to follow the directions, and updating is not occurring "automatically" as stated in all of the problem solving descriptions. When I get certain instructions, it refers me to a "Settings" button, which does not appear/exist on my toolbar(s). This latest inquiry is related to my original question about "licensing" issues error message when trying to view Youtube rented video's. Also, how do you go about updating a Widevine setting, mine is currently 4.10.1582.2. and needs updating. Please help me, I would like to learn how this stuff works, I appreciate any help.
