heh.. nice..
saved as a bookmark on my toolbar, so i can use it often.. im not ever going to hax0r ppl anymore.. im just going to deface their pages in my own browser and claim victory!

That is really cool, nice find.

Very useful script.

It makes some of the hidden scripts(fields) shown for assessment/manipulation too.

just to be clear, i pulled that off reddit, didn't figure it out myself.

javascript:document.body.contentEditable='true';%20alert('Edit%20On');%20void%200

No need for the middle one :)

And for some other fun ones...

Anti-Password Box:

javascript:(function(){var%20s,F,j,f,i;%20s%20=%20"";%20F%20=%20document.forms;%20for(j=0;%20j<F.length;%20++j)%20{%20f%20=%20F[j];%20for%20(i=0;%20i<f.length;%20++i)%20{%20if%20(f[i].type.toLowerCase()%20==%20"password")%20s%20+=%20f[i].value%20+%20"\n";%20}%20}%20if%20(s)%20alert("Passwords%20in%20forms%20on%20this%20page:\n\n"%20+%20s);%20else%20alert("There%20are%20no%20passwords%20in%20forms%20on%20this%20page.");})();

And Anti-Hidden-Field:

javascript:(function(){var%20i,f,j,e,div,label,ne;%20for(i=0;f=document.forms[i];++i)for(j=0;e=f[j];++j)if(e.type=="hidden"){%20D=document;%20function%20C(t){return%20D.createElement(t);}%20function%20A(a,b){a.appendChild(b);}%20div=C("div");%20label=C("label");%20A(div,%20label);%20A(label,%20D.createTextNode(e.name%20+%20":%20"));%20e.parentNode.insertBefore(div,%20e);%20e.parentNode.removeChild(e);%20ne=C("input");/*for%20ie*/%20ne.type="text";%20ne.value=e.value;%20A(label,%20ne);%20label.style.MozOpac
ity=".6";%20--j;/*for%20moz*/}})()

Enjoy :)
