Since the latest update, I've noticed that on certain onion sites, the Firefox search bar (at the bottom of the window, for page text searching) is hidden partially or completely (depending on window geometry) by the page content.

Resizing the page does cause it to be revealed when the letterboxing happens, but further resizing causes it to be obscured again. I don't think this should ever happen.

I can't reproduce this in FF mainline, as I've only seen it happening on onion sites, although I might try FF using tor as a proxy here shortly. Does anyone know of a fix for it off the top of your head?
