Can someone tell me why FireFox is displaying scripting.com in Chinese characters?

I downloaded Mozilla FireFox on the first day version 1.0 was released. I was impressed and glad. I could finally switch from Internet Explorer to another browser.



However, two days ago things started going wrong. First FireFox started showing little black diamonds on this site.

Yesterday I was reading Dave Winer's daily newsletter in Outlook and clicked on a link to his site. I got the above result - all Chinese characters. It also doesn't matter how I open the site either. Rebooting doesn't help. I've tried changing fonts and default character encoding but that doesn't seem to make any difference.

I've changed back and have made IE my default browser again. It's a bummer...
