It's good that you mentioned it, but it should be said that the experience is far from perfect (at least in FF). Playback speed resets at every question break, each new video, etc. Audio drops out of sync frequently and seems to have more issues when sped up than in VLC.

I have had little to no issues with quality of playback in Chrome. However, like your sibling comment suggested - it does lack keyboard shortcuts.
