I had to turn off my anti-virus app for a few minutes. When I turned it back on I had apparently been hit by at least one virus. One of these viruses attacked my Firefox search settings. All of my search engines in Options->Search have disappeared and I cannot reinstall them. I have attached a screenshot for your enjoyment. AVG did find several viruses and says they were eliminated. It also installed AVG SafeSearch. However, when trying to search using that engine, nothing happens...like I click search and there is no response at all. It also appears that it has affected my ability to use Firefox Support in Firefox as I tried to submit this question and it crashed Firefox....not I have to use...<cough><Gag>Chrome. Suggestions? Thanks in advance.
