Polyfill doesn't work in firefox 47

[marcog83]

Hi, I was exited about EventListenerOptions, so I started use this polyfill in my project.
It works fine in all my supported browser, but firefox . I don't know exactly why, but it blocks my scripts.

by the way thanks for your job.

Thanks for the report. @dtapuska have you tried your polyfill in Firefox? Newer version of Firefox have the API built-in, but having a working polyfill would still be good IMHO.
