Method I
Use SkipScreen. It is a free Firefox add-on that lets you skip all the clicking and waiting on sites like RapidShare, Zshare, MegaUpload, and Sharebee. Your downloads start instantly. All you need to do is to install the add-on, and open all the rapidshare links on a new tab. You will notice that SkipScreen tries to download all of the links but only 1 will get through and the rest will say that you are already downloading a file. Once the first file has finished downloading, SkipScreen will automatically starts to download the other parts…

Method II
In this method we can use a Greasemonkey script called RapidShare AutoWait. This script only works on RapidShare and it even hides the advertisements in RapidShare. First make sure you have Greasemonkey add-on installed, then click here to install the RapidShare AutoWait script.

Both methods above will still need to wait all those timeouts and countdowns, but you won’t have to sit in front of your computer to do that.
