  • All the mochitests under browser/base/content/test/general have a fix, not all the fixes have landed yet though
  • I've moved to fixing the tests under dom/base starting with the ones affecting the clipboard, progress is slow since I'm unfamiliar with this code and the first one I tackled turned out to be a real issue in Firefox when running with e10s enabled
