Redirecting from menu home button - video loading aborted error

I am doing a redirect from inside the video either when the video ends or someone hits the menu button. Everything works in chrome and safari but for some reason firefox gives me the error below.

Error: http://url.com/video.mp4 - video loading aborted

My code is just place javascript below:

<![CDATA[          window.location.href = "http://someurl.com/somedirectory";
]]>

Is there a way I can turn off errors or force them to the console?
