in firefox, when main window, press ctrl-shift-A. then in the addons control panel, remove whatever you want, and if you use firefox 3 or older, download firefox 4.0 from mozilla official.

I guess I'm a slow learner. How do I get to the "main window"?

Go to this page https://support.mozilla.org/en-US/kb/uninstalling-toolbars?s=uninstall+toolbars&r=0&e=es&as=s

It's NOT a toolbar, it's an ADD-ON

You need to restart Firefox and be sure to tell the splash box to "go away", then restart again and the toolbar will be gone.

I have done everything to get rid of this d*** aol toolbar (dlink associated). Removed every query for "aol", "dlink", and "toolbar" using regedit and windows explorer - Fired up Firefox, and it's still on the browser. It is also insidious, whereby it tries to change my home page & does change my search engine (to "AOL"). This happens every time I use Firefox. I may dump firefox for google "chrome" if I can't get this toolbar off.
