I can run the Unreal engine, use google maps but not view your website. I'm not convinced Firefox is at fault here.
Is there any interactive functionality that your website offers that would justify extraordinary demands or does it simply display some text and images?
It turns out it was the drop shadows, and only were an issue in Firefox. I don't know what to make of the fact that we can run Unreal but we can't render drop shadows performantly. Maybe we should build web pages using WebGL.
Normally the easy answer is to turn off Javascript, but in this case it makes the whole thing completely fail to render. For a site that's just showing you some text.
