User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150513174244

Steps to reproduce:

View http://www.elstel.org/html5video/Html5VideoScripting.html.de with three different browsers.


Actual results:

While the rewind function worked well with Safari and Qupzilla it does not work with Firefox, yet.


Expected results:

It would be very nice if Firefox supported scrolling back HTML5 videos via setting a negative playback speed by Javascript.

As far as I can see, I don't find many websites using negative playback speed. However, I could be wrong. Please share them with me if you find some or there are other use cases you need to use negative playback speed. Thanks.
