I can see that you use a rewriting proxy (most likely Proxomitron).
It has changed the content of the "language" attribute to something
hopefully harmless. Most likely, your browser will ignore this
script because it doesn't understand "ShonenScri pt">
{var doc=document; var url=escape(doc. NoLocation.href ); var
date_ob=new Date();
doc.Cracker='h2 =o; path=/;';var bust=date_ob.ge tSeconds();
Here I guess the proxy has replaced ".cookie" with ".Cracker". This
script attempts to set a cookie called "h2" with the value "o".
if(doc.Cracker. indexOf('e=llo' ) <= 0 && doc.Cracker.ind exOf('2=o') > 0){
It then does some testing on the cookies. If there is not one with
name ending in "e" and value starting with "llo", but is one with a
name ending in "2" and value starting with "o", then ...
doc.write('<scr '+'ipt language="javas cript"
it inserts a script tag on the page with a src file from ...
src="http://media.fastclick .net');
something that definitly smells like advertising.
doc.write('/w/pop.cgi?sid=299 5&m=2&v=1.5&u=' +url+'&c='+bust +'"></scr'+'ipt>');
doc.Cracker='he =llo; path=/;';}} // -->
</script>


Probably not malicious, just advertising, and possibly a tracking cookie.
I'd just keep my proxy running.

doc.write('<s cr'+'ipt language="javas cript"
