allows you to easily add files to the download list of MLdonkey : you only have to click on the URL of a file (the URL begins with ed2k:// for eDonkey2000 and fha:// for Overnet) and the file is automatically added to the list.
Safari users : clicking on an ed2k:// link does nothing in Safari. You will have to drag the link to the address field.
NOTE : OmniWeb does not work with DonkeyHelper (yet?).
