Well, this idea has been floating around for years (since the httrack
begining, actually), but is has some drawbacks:
- not so easy to package (the mozilla code is not that flexible)
- slow to process a page (mozilla is a bit sloppy, as internet explorer is
also BTW)
- not an absolute solution (some links would be missing anyway)
