Disappointing but not unsurprising given the demographic of the sites. Think about it. Most people who are in to modded cars are young men/teens(at least where I live anyway) i can't see them going to any trouble downloading and installing a browser. Their going to use whatever is there and that they're used to. Granted there are always exceptions to the rule but the results for that particular site confirm it.

I'm surprised that firefox has such a large chunk in many of these sites!
