There does seem to be a way to stop Greasemonkey from working, as I  
found out by accident (see this thread: <http://mozdev.org/pipermail/ 
greasemonkey/2006-March/007977.html>).

If you serve your pages to Firefox as application/xhtml+xml, save the  
following as a file called block.xsl in the root of your site:

<xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/ 
Transform'>
	<xsl:template match="*">
		<xsl:copy-of select="."/>
	</xsl:template>
</xsl:stylesheet>

and put
<?xml-stylesheet type="text/xsl" href="block.xsl"?>
at the top of your pages (just before the DOCTYPE), then Greasemonkey  
won't be able to run.

Of course, this relies on your pages being valid XML, otherwise they  
won't display at all :-)
