See https://bugzilla.mozilla.org/show_bug.cgi?id=973849 and duplicates.

The fix I'm doing for Gecko is this:

-  void clearTimeout(long handle);
+  void clearTimeout(optional long handle = 0);
-  void clearInterval(long handle);
+  void clearInterval(optional long handle = 0);

Since 0 is never a valid handle value, this automatically makes the methods no-ops when called with no arguments.
