Love it!

Simple and unobtrusive, does the job. Needs more customizations though:
1. Option to disable keyboard shortcuts altogether. I don't need these HTML5 video features often enough to warrant assigning shortcuts to them. Also, I use extensions like VimFx or Saka Keys, and it's messy and unnecessary to have two sets of shortcuts like that.
2. Option to customize what buttons we have in the controller. I rarely need the advance/rewind buttons (which crash Netflix video playing, btw), and I need a 'reset to 1.0' button in the controller very much. Being able to customize these would be great.
3. Minor one, but an option to customize which corner of the video the controller appears in. As of now, top-left is the default, but being able to customize that would be great.

Fantastically useful addon, saves buckets of time, makes it easier to search HTML videos. Lovely

Good extension to control speed, I personally use keys + and - to control it (like a similar chrome extension)
Good customization :)

Works simply perfect with Vimeo which is exactly what I needed it for. The customisable shortcuts are a nice plus too!

BEST TIME SAVING APP EVER.

Seriously, had some coursework with professors from Texas that talk like snails crawl: sllllooooww.
With this extension, their unbearable 4 hour videos got reduced to a more reasonable 1.5 hours at a quicker pace.
I started training my brain to hear info faster in videos and as a result, start most videos at 2.0x speed or more just to save the time.
Would pay for the pro version considering how useful this extension has been and amazed that it's free ninety-nine!

Amazing

well done
