Some of the special characters were mangled by the forum so please edit your post and place the original bookmarklet code between <code> </code> and delete the converted userscript code since it's not helpful anyway.

and don't forget to visit http://jsbeautifier.org/

No, don't use jsbeautifier - it destroys this code, I already tried it.

jsbeautifier isn't guilty, the posted code is damaged.

forum's parser removed pieces of code following after `<` char

thanks for the reply here pastebin
http://pastebin.com/dJK3jry7 for correct code

i d like to convert it to a userscript for chrome /firefox to run automatically

MutationObserver is required in this case :(
