It is working for me in Firefox 6 and 7, but not in Firefox 3.6
Make sure that DOM Storage is enabled and that you do not block cookies.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

The website is loading fine on my system too.
-> Clear Cookies & Cache
-> Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
Check and tell if its working.
