Did you spell Javascript wrong, or did the website?

That is an error in that page code under Browser Requirement:

JavaScript must be enabled (test) : javasript:TestJavaScript();

You can use this if you like (paste in the location bar):

javascript:TestJavaScript();

I've had this issue for a very long time. According to my options, javascript is enabled in Firefox. I think I messed it up a while back futzing around with an addon I can't recall the name of. This is especially annoying when trying to watch videos on YouTube or check prices on Amazon (which pops up the error message like eight times). I've tried uninstalling and reinstalling Firefox multiple times, but it's followed me all the way through every version of 3 and into 4. I've been ignoring it and just using Internet Explorer on JS-heavy pages, but that's not really ideal.

I just fixed this problem on mine.

type about:config in the address bar.

filter with the word javascript

A config variable will be in a bold font if it has been changed from the default value.

network.protocol-handler.external.javascript

was bold when I reset it back to the default by right clicking and selecting reset, javascript began to work immediately.
