Rapidshare Find could be of aid to you as well. The whole purpose of this Firefox add-on is to copy Rapidshare links (and links from other file hosters) found on websites. These links can be copied to the clipboard and are then either automatically picked up by a Rapidshare download manager or by manually adding them to the queue of that download manager.

The add-on offers another option instead of copying the Rapidshare links to the clipboard. It is possible to open all selected links in separate tabs. I don’t like this option that much because it means that you still have to endure the wait timer at Rapidshare, the download manager (like USDownload) is a far better option.

The add-on adds a button to the status bar. If you click that button the add-on will compile a list of all available links and present them in a popup window. Select the links that you would like to copy (or open) and click on OK.

Rapidshare Find supports 15 websites that host files including Rapidshare, Megashare and Sendspace. Each of them can be checked to be included in the parsing of the website.

I previously compiled a list of Rapidshare Search engines which could be used as a starting point to search Rapidshare.
