Well, greasemonkey can execute users script but only after the page loads fully. Is there any script that can take user script (javascript) and executes it before the page downlaods any elemts. for instance, As soon as the HTML file is downloaded, the user script should execute so that i can prevents the download of embedded elements like flash, jpg, js files downloads
