Thanks for the link. I'm only having the problem on Facebook so far. There is no text overlay or missing buttons, just the frames are all jumbled up and in the wrong place. Reloading the page sometimes causes a frame, or all of them to disappear completely and I get a blank white page.
I've tried clearing the cache, allowing Facebook in no script, etc, but the problem persists. Not a huge deal as it's only one site and I can look at that in Chrome with it's nasty skinny little fonts if I have to.

My bad. The same behavior just happened using Chrome, so I guess it's a Facebook issue.
