From Firefox to Safari, maybe

I'm having an infuriating problem with Firefox lately, and I might have to switch to Safari, even though I really don't want to. It's a strange redraw problem when I scroll up. This just started a few days ago. I can scroll down, but when I scroll back up, it compresses all the images and text into this mess that looks kind of like sedimented layers of rock, but made out of web page instead.

Okay, wow, one second after I hit "post," I went to View --> Status Bar, and it stopped. Crisis averted, and I get to keep my lovely lovely Firefox with its lovely Pimpzilla theme.
