Huh. Google’s Chrome browser uses a different onmousedown handler for tracking GOOG’s search result clicks:

Firefox handler:

window.clk = function(b,c,d,e,f,g){
   if(document.images){
       var a=encodeURIComponent||escape;(new
Image).src="/url?sa=T\x26source\x3dweb" +
           (c?   "&oi="+a(c):"") +
           (d?"&cad="+a(d):"") +
           "&ct="+a(e) + "&cd=" + a(f) +
           (b?"&url="+a(b.replace(/#.*/,"")).replace(/\+/g,"%2B"):"") +
           "&ei=dVvtSLTSFYnOsAOipLX-Aw"+g;
   }
   return true;
};

Chrome Handler:

window.asq = function(d,a,e,f,h,i,j) {
   if(window.XMLHttpRequest){
       if(a.handledFirstTime){
           a.handledFirstTime=false;
           return false;
       }
       a.handledFirstTime = true;
       var b = encodeURIComponent || escape,
       c=new XMLHttpRequest,
       g=d.altKey||d.metaKey;
       c.open("GET","/url?sa=T\x26source\x3dweb" +
              (e?"&oi="+b(e):"") +
              (f?"&cad="+b(f):"") +
              "&ct=" + b(h) + "&cd=" + b(i) + "&url=" +
              b(a.href.replace(/#.*/,"")).replace(/\+/g,"%2B") +
              "&ei=OlvtSLOELKGksQObytH8Aw"+j,true);
       if(!g){
           c.onreadystatechange = function(){
               if(c.readyState==4){
                   clearTimeout(k);
                   a.dispatchEvent(d);
               }
           };
           var k = setTimeout(function(){
               c.abort();
               a.dispatchEvent(d);
           },2000);
       }
       c.send(null);
       return g;
   }
   return true
};

Why not use XMLHttpRequest in the Firefox version? Are some Gears
back-door shenanigans afoot? Anyone know? -Ben
