so useful, even can speed up audio (BBC Sounds) and works well with preset speeds

very happy this was ported from Chrome :)

This is a much needed and appropriate port from the best Chrome extension for video controlling. Works great, unfortunately it doesn't seem real that it would work starting from Firefox 48 as described. As I'm using Waterfox (FX 52 ESR equivalent), v0.5.1 is the only one really doing the job (attachShadow problems).

doesn't seem to work for amazon prime video, at least not correctly (doesnt visually show speed change in the extension UI), the speed might change only sometimes when the buttons pressed on amazon prime vid. only site I have issue with

Works very very well, but stops working whenever I use an equalizer addon to filter out some background noises.

Hi, I added this extention to use on my android phone, but it isnt designed for mobile use is it? Can you advise?
Thanks

excellent app

each press of the button expands the video screen into full screen mode, and then the next button decreases it to normal dimension. entirely frustrating and unnecessary.

I really have appreciate this app. I can run through video material - particularly lectures in much less time. a tip: learn the shortcuts and customize it to you preferences . If you train yourself to use its features, its utility will become even greater. I like to turn on closed caption, which allows me to run faster and still keep up. I would like to see a single button that would back up X seconds and then play forward at X (slower) speed. A second button returns you to your last "cruse speed". Also being able to reprogram some other keys for preset speeds would be real nice I dream about having a separate custom key pad set up for it. :-)

conflict with translatesubtitles.com, the translate box dont show up when using TRAN SLATE/EDIT SUBTITLES section, found out cause by this extension, disable it the problem gone

Audio is not good when u go for 2x and above.Please work on audio (android add-on)

Simple and super useful

Simple, works well, saved me hundreds of hours, can t watch videos without it now !

Light and simple addon. Does what it says.

SUGGESTIONS:

1) Add a whitelist option too. I only want this for Netflix (although " .com -Netflix " does the job)
2) Option to only show Overlay when speed is altered

Works just as intended.
