That and as far as I know, Firefox is the only browser that allows you to enable/disable specific Javascript features. Safari, Lightning, Roccat, Sunrise, and Firefox's cousin Camino can only turn Javascript on or off. The Google browser Chrome and its open source sibling Chromium don't even have the option to turn Javascript off unless it is in the developer tools. Which is why the site worked for everyone using different browsers.
