Cool Firefox Trick
 

Go to google and copy and paste this into your Url:

javascript:x=0;e=document.body;e.style.position="a bsolute";function rt(){e.style.top=100-(50*Math.cos(x*Math.PI/180))+"px";e.style.left=100+(50*Math.sin(x*Math.PI/180))+"px";x+=5};setInterval("rt()",50);void(0);

Bookmark for easier access
NOTE: ONLY WORKS WITH FIREFOX (I think)

No thanks, my about:config is working as intended.

I went to Google. I pasted the thing into both the URL and, when that failed, pasted it into the search box. Neither item did anything.

Thanks for this.
