Thanks but its not really complicated. I already have script based on taos's post. It automatically displays the RapidShare link without any delay or any user action.
Just install http://greasemonkey.mozdev.org/ in order to use attached script.
Instruction: drag following script on firefox, click Tools->Install User Script.
Thats it. Now whenever you visit RapidShare Free link, it will immidiately displays the URL (which you would otherwise see after delay). Very simple ( I prefer open source

)
