Moves the find bar in Firefox to the top of the window and nothing else.

All and total credit to KuRmA's awesome style here: http://freestyler.ws/style/100719/find-bar-like-google-chrome I take NO credit for this whatsoever. I just released it to help anyone who ran into the same problem I had, which is most of the changes don't work well with a transparent firefox. So this is vanilla, just moves the find bar to the top and nothing else.
