  • Very good, works as advertised. It's just that even with a modern 6-core 4.5Ghz CPU and 32GB of RAM, the sound quality in speed-up is really bad (much worse than Enounce Myspeed or many Chrome extensions doing video speed up).

    If the author would improve the sound quality (give a selection for low-cpu-impact/bad quality and higher-cpu-demand/super-quality audio algo), then it would be perfect 5 stars.

  • Luv it

  • Best add-on ever. Pls make a safari version.

  • Todo

  • I use this all the time, saves me time...lots!
    Controls work well and remain subtle and unobtrusive during video playback.
    The "1.00" is easy to tune out, even on Netflix.
    Super job!

  • used to work flawlessly on firefox for android up until a recent update was released, now everytime you load up a video the controls stay onscreen for 5 seconds and then disappear. the only way to get them to show up again is to pause and unpause the video.

  • Must have

  • Fantastic

  • I love it but it doesn't show Sometimes

  • nice

  • Très pratique pour accélérer les MOOC

  • it's an amazing, useful and easy to use extension.

  • Simply the best!

  • Great add on.

  • At last a port of Video Speed Controller for Firefox, thank you! Being able to adjust the speed with shortcuts is essential to me. It's like being able to read a text at the speed I want. Thanks again.

  • Exactly what I wanted!

  • Stops working after 1-2 videos. Only way to make it work again is to remove and add it again.

  • 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!


    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
