ok, for those who wants to add highlight ability to code (display only, not when editing) I have created workaround using greasemonky on firefox.
what you need:
on firefox:
1.install greasemonkey addon
https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/?src=ss2.install the usescript `HighlightMe.user.js`(attached) by drag and drop on open firefox.
3.enabled greasmonkey and the script.
on google chrome
1.install Tampermonkey
https://chrome.google.com/webstore/detail/dhdgffkkebhmkfjojejmpbldmpobfkfo2.open `HighlightMe.user.js` with any editor then copy its content.
3.on chrome click the tampermonky icon then Add a new script after that paste the copied script.
4.click setting tab and change `Run at : document-start` and `Run only in top frame : Yes`
5.Save.
EDIT: edited the HighlighterMe.user.js ; to work with changes to the last forum code highlighter.
I'll still use it since the forum code highlighter doesn't work with old posts.
EDIT2: corrected some errors on the script.
