I'm back in business - thank you all, Project and the others who tried to help.
This is gonna sound dumb, probably, but I am beyond caring if it does.
I have been running Firefox on Version 11. I downloaded Version 12 three times at their invitation (from the official Mozilla site I thought) and each time it came with something that was apparently hitching a free ride on the download--it was some kind of MP3 Tube tool bar that I didn't want and couldn't get rid of. I still had the "setup Version 11" icon on my desk top, so I reinstalled it and it worked OK. Then I got into trouble with the problem that I started all this with.
I tried everything everyone suggested, thank you one and all. Firefox had bugged me for a long time to download Version 12 so I tried that AGAIN (not knowing there is now a 13) but it wouldn't download. I finally got Version 13 up and running, but it has taken me several hours to get it back so that I have "file, edit, view, history, bookmarks, tools, help, back arrow, refresh, etc. etc." Whew! It is very hard to live without tools and at least a back arrow!
I hope Firefox won't want me to "upgrade" again soon. I have had problems with every single upgrade that came along since I first heard of that browser. PAH!
