If you use Chrome, a better option is to use Video Controller extension[1]. Works with any html5 video, and gives you a lot more granular control.

I use this every day. Being able to quickly jump forward/backward 10 seconds is also very useful. I recommend setting keyboard shortcuts that agree with equivalent functionality on your desktop player like VLC.
