Hi Alice0775 White, can you let us know which "Search Bar" you're referring to?  (Sorry, I don't know the names of things in the FF UI very well ;) ).

Suspected dup of bug 795576.

I can reproduce this. It's the search bar in the navigation toolbar.

Thanks!  I can repro on win7/d3d10 (my linux FF doesn't have a search-engine bar).

I'm about 99% sure this is fixed by bug 795576.
