javascript - spacebar not cancelling default event on firefox -

i'm building video player , 1 of features related toggle play when hit spacebar , execute process within. works on browsers except firefox. if hit spacebar , video paused, plays less second , gets paused. there i'm not aware of causing behavior related firefox?

player.addeventlistener('keydown', function(e) {     if (e.keycode === 32) {       if (player.paused) {          player.play();       } else {          player.pause();       }       // ... other actions event       e.preventdefault();      e.stoppropagation();    } }, false); 

firefox triggers click event when using space bar. using conditional avoid firefox when pressing space bar fixes it
