You can check if you see that search engine in the searchplugins folder in the Firefox program folder.

• (32 bit Windows) C:\Program Files\Mozilla Firefox\
• (64 bit Windows) C:\Program Files (x86)\Mozilla Firefox\

I hadn't thought of looking there, so I checked and sure enough, there it was. I deleted the file, then checked the defaults--nope, it showed up again. So I shut down Firefox and restarted my computer. Opened Firefox, clicked on "restore defaults" and Babylon showed up again. However, when I looked in the folder, it wasn't there any more. So I started going through all of the Mozilla folders, and found it in Mozilla Firefox/updated/searchplugins. So I deleted it again, checked the defaults, and boom, there it was. That thing is insidious and I don't like having something on my computer that I can't get rid of, and that hides itself. Thanks for your help, though--I'm going to have to keep trying. Malwarebytes didn't even turn it up, so the next step is to try Spybot.

You can use the MSConfig program or the Autoruns utility to see which software and services are getting started.

Try to do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.

Download a fresh Firefox copy and save the file to the desktop.

• Firefox 19.0.x: http://www.mozilla.org/en-US/firefox/all.html

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

• Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

• It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

If you keep having problems then also create a new profile.
