I think the problem is in css file of http://www.pragprog.com/, especially, high.css file.

I downloaded main html file and css files from the site to my local machine (xubuntu 8.10, restricted nvidia driver, FF 3.0.1) and tested with some combination of them. Finally I think I found the root of trouble.

You can see below code in high.css file.

body {
  background-color: #858072;
  color: white;
  padding: 0;
  margin: 0;
  -moz-opacity: .99; /* Firefox bug fix */
}

The last line "-moz-opacity: .99; /* Firefox bug fix */" is today's main guest. It's a kind of trick for solving FF 2.x bugs.
However, in FF 3.x, it makes our headache. :-)

I hope The pragmatic bookshelf removes the line or changes value from .99 to 1 or Firefox team makes patch to around this kind of crash.

Or... you can use alternative way to solve this crash with stylish plugin. I'll explain how to do it in my blog (http://classpath.egloos.com/4622029). It's Korean blog, but I'll try write it in English.
