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. 101252 2 ian 2014-02-24 18:45:08 +0000 done as suggested
