That string of odd characters is what you get if you try to read in this ASCII string: > with (document) > { > write('\bVersion: 1.0.0 - 12-13-2004\b'); > } as UTF-16. Firefox is simply complaining that the odd characters don't appear to be executable JavaScript of any sort. The problem is that your web server is serving JavaScript files with the header: Content-Type: text/javascript However this does not tell the web browser what character encoding the file is using. So it has to guess. Firefox's guess is "the same encoding as the HTML page that referenced it". And for some reason your HTML page is saved as UTF-16, an encoding which uses two bytes per character instead of one, and hence one of the few encodings that isn't compatible with US-ASCII. To fix, either make the server specify a character encoding for JS files by sending a header such as: Content-Type: text/javascript;charset=utf-8 or save the HTML file in a format compatible with US-ASCII. UTF-8 is a good choice. Windows calls the UTF-16 format "Unicode" when you save it, which is pretty misleading and might have lead to this inappropriate choice of encdings to save under.
