enabling Magnet links
 

I don't know if this is the right place to ask this question, but here goes:

How do I enable Magnet links in my browser (Mozilla 1.7)?

If I click on a download link on :

http://www.magnetmix.com/

I get this error message:

<b>Magnet is not a registered protocol</b>

The FAQ on this site is not so helpful; it simply says you need LimeWire installed (which I do of course).
