Update: Thanks to Thomas, we could use the linkify addon

Sometimes you might stumble on some sites where gives you a list of rapidshare link (not really a link) and you want to download all of it, you cant do Ctrl + click, or Open All Urls in new tab on firefox tab mix plus. So how to do it? This requires you to use the terminal, vi, premium Rapidshare account and Unix base OS (sorry windows user, you can still do this but your on your own).

First stuff is make sure your Rapidshare uses Direct Downloads, which will not redirected to Rapidshare and will give you the download file, this can be configure under settings .

Next copy the rapidshare links.

Next open your terminal and make a file.
>> touch rapidshare1.sh
>> vi rapidshare.sh
Press i or a, then enter the location of the shell usually /bin/sh
#!/bin/sh

Next paste the copied links to vi (this will depend on which terminal you use)
Next is to do a string replace, press esc and enter
:%s/^/\/usr\/bin\/firefox ”
Press enter, and press esc again
:%s/$/”

The first one replaces the front of the string with a command that will call firefox to open with the link that you gave it, the second is just a closing quote. Now you can exit vi (press esc and type :wq)

Next make your file executable by
chmod +x rapidshare.sh

Next execute your file
./rapidshare.sh

Done.

Btw, you might also consider to install DownloadThemAll extension on firefox and set the settings to 4 Max Concurrent Downloads and on the Advance tab set the number of chunks to 1 (This is important or less you might be ban by rapidshare for downloading too many thing at the same time). Then next time you download pick the DownloadThemAll as default.

Happy rapidshare downloading
