Javascript creates a lot of trouble as used on some sites, even on desktops (some of the javascript is so Windows- or IE-oriented, or both, that it fails miserably on other platforms). And what Moonshine describes for WSJ and CNN is, I guess, typical web-designer-trying-to-be-too-smart-for-his-own-good. Or possibly that would apply to the web design "tool" they're using.

In any case, what I really was about to say was that Firefox has extensions.. one of them is per-site enabling of javascript. Now that we're going MicroB, maybe extensions wouldn't be out of the question a bit further up the road..
