A javascript bookmark to add bookmark from chrome

Evernote creates a Javascript bookmark with the following code:

javascript:(function(){EN_CLIP_HOST='http://www.evernote.com';try{var%20x=document.createElement('SCRIPT');x.type='text/javascript';x.src=EN_CLIP_HOST+'/public/bookmarkClipper.js?'+(new%20Date().getTime()/100000);document.getElementsByTagName('head')[0].appendChild(x);}catch(e){location.href=EN_CLIP_HOST+'/clip.action?url='+encodeURIComponent(location.href)+'&title='+encodeURIComponent(document.title);}})();

If you had something like that to post a URL to foxmarks, then Chrome, Safari and Opera users would have a way of adding bookmarks. It would also work for people who could not/do not want to add a firefox extention.
