I'd be happy to do that.  Is the following correct?

  The UI and rendering libraries that were part of the
  mozilla-firefox 2.x package have been split from the mozilla
  firefox-3.x package and are now in the xulrunner package.  In
  order for ebuilds to use xulrunner instead of mozilla-firefox
  2.x, the "firefox" USE flag must be replaced by the
  "xulrunner" USE flag.  Failure to replace the "firefox" USE
  flag with the "xulrunner" USE flag will result in portage
  requiring mozilla-firefox 2.x which is incompatible with
  mozilla-firefox 3.x -- this will block some packages from
  building.
