I have used firefox for many years and have it on two computers.However due to problems dealing with the bing search bar accidentally somehow lost my login identity on one of my computers and now cannot upgrade firefox even though I can use the existing version and still have the valuable memorised passwords. (I may never have had a firefox password as Mozilla was always the go to source for help.) I use the same e mail address for both machines and wonder would like to know whether I can find my account login on this machine to restore my connection with the other machine. I don't know how to find my password thanks terence christopher
