In Firefox 2: javascript:s='<?>';for(i=0;i<1006;++i)s+=' ';window.location='data:text/html,'+s+'<!doctype html><script>document.write(document.compatMode)</script>' javascript:s='<?>';for(i=0;i<1007;++i)s+=' ';window.location='data:text/html,'+s+'<!doctype html><script>document.write(document.compatMode)</script>' The first produces CSS1Compat, the second BackCompat. As far as I can tell, Firefox requires the doctype to be found when parsing [using standards-mode rules] the first 1024 characters (not bytes) from the first non-whitespace character, and then it reparses the whole document in quirks mode if necessary. -- Philip Taylor excors at gmail.com
