When I opened Firefox this evening I was reading my emails when it unexpectedly closed. I tried to reopen and an entirely new screen appeared. I tried to get into email and it was impossible to find. All my bookmarks have disappeared! This is outrageous! I have critical addresses that I have to contact in my business which are part of the bookmark list. What has happened to my old lists and to my email account?

Look on your desktop. Do you see a folder called; Old Firefox?
