  16          * Known to be fixed in 1.2.1 (Gecko 20021130), but the CSS hacks I've tried with overflow-x disable the scrolling
  17          * all the way until Mozilla 1.8 / FF 1.5 and break Opera as well.
  18          *

  20          * scrolling them. Not ideal as it won't work if JS is disabled, of course.
