I've been using Video Speed Controller and it makes adjusting playback speed on any HTML5 video effortless. The fine-grained control and keyboard shortcuts are very convenient for lectures and tutorials. It remembers settings per site and feels lightweight, reliable, and smooth without interfering with normal viewing experience at all sessions.

I've tried a whole bunch of add-ons from outdated versions of this add-on, and this is the only add-on that works great with vkvideo.ru . Thank you for continuing to contribute and improve this add-on.
