In fact it should be possible to create a firefox extension/addon to do it.

That might be a bit too simple, though. as I read it, pages can be interfered with - legitimately - by adblockers, pop-up blockers, etc. I've not looked in detail at how the web tripwires work, but the authors seem to have some comprehensive data indicating WHAT has changed the pages.
