Very lightweight script that automates downloading on rapidshare.com. If you klick any rapidshare download link, this script will select "free download", wait until the counter is finished and start the download - without any clicking required.

// @description If you klick any rapidshare download link, this script will select free download, wait until the counter is finished and start the download - without any clicking required. It uses/manipulates rapidshares builtin javascript functions, thus looking exactly like rapidshare does by default (which may not be very pretty) but beeing comparatively reliable.
