This is what I see in FF console (no playing event, in Chrome can see that event, thanks):

on firefox v38.0.1, i see those errors you mentioned, but they're coming from inside YouTube's official library, which i have no control of

in the middle of those errors, i also see playing!!!, so the event is firing

since there are tons of those This site makes use of a SHA-1 Certificate; it's recommended you use certificates with signature algorithms that use hash functions stronger than SHA-1.[Learn More], are you sure you're not overlooking the playing!!!? could you change the console.log to an alert to verify?

thanks again

I've checked it again, after clear browser cache (js, css etc.) - works.
Thank you for help!
