Javascript code edit

[ethanara]

i learned this thing from one of my friends.
go to a site, for example google.com
then delete google.com in the adress bar and paste this little code in:
javascript: document.body.contentEditable = 'true'; document.designMode = 'on'; void 0

then you can edit the whole site, but you friend cant see it if he goes on google
if you wouldnt do that anymore goto google.com again

one of my friends tried this on google while we talked in skype, and he got a little shock and said "ups, i deleted google!"
