If you're going to run Hijack This as many are suggesting, you're going to need to have your Hijack This log analyzed.
After you run Hijack This, you'll get a log in notepad. Copy that log and paste it into the box as the following site:
http://www.hijackthis.de/index.php?+langselect=english
Click submit and follow the directions you get.
Good luck.
Extricating an extension without Firefox running is possible if you know what you're doing since everything's an editable text file. Mail me if you want to try it.
"Creative Commons" is a flexible set of relatively open licenses for copyrighted works, and a pretty good idea (more here). I believe Yahoo recently started a Creative Commons search feature, and that could have been in the toolbar.
There have been cases where Firefox didn't open yet it was running in the background, even multiple times, which is a drag on the system. Do Control-Alt-Delete and see if it's showing and close it/them.
