Your HTML markup has some errors (such as a div tag inside an h1 tag) that should be fixed before you try to analyze a crash.

The div inside h1 apparently caused a cascade of errors that the validator had to suppress to continue.

When I have browser crashing problems, HTML validation is always my first step. Then I try seeing what might be wrong with the javascript if correcting the HTML didn't help.
