After stupidly updatig Firefox, I found it DID NOT save my preferences and former settings. I went through Settings and set everything to what I think I had before, but now every, and I mean EVERY website is displaying ads that were not there before. I am uninstalling Firefox as soon as this page is exited and will be using Edge from now on. At least with MS, I know they are going to do their level best to annoy me. I expected better from Firefox. Bye!
