[Greasemonkey] add prefetch attributes

[Leo Zelevinsky]

Hi all!

I would like to take advantage of the prefetch feature of firefox on
non-prefetch-aware webpages. Can I use Greasemonkey for this? I did
some searches with no luck.

It seems like it should be relatively straightforward so I'm wondering
why I can't find anything. For instance, I'd want to add to a link
that says "Next" the prefetch attribute automatically.

Any pointers would be much appreciated. Thanks!
