Works well. Works on Udemy also.

Video Speed Controller is great! Small and unobtrusive, and it does exactly what it says! Well conceived, and elegantly executed!

شكراً جزيلاً على خدمتكم لنا

me ajuda muito nos estudos

There seems to be a bug I was experiencing with this add on. On a couple of webpages I was having an issue where the javascript was being blocked, but the pages worked fine when in safe mode. After deleting this extension, the problem seemed to be fixed. This is a good extension when in use, but I can not tolerate my browser being broken in the process.

Edit: The newest update seems to have fixed my issue, thank you!

Great tool!

Works great! Thank you for crating this extension!
Suggestions: could there be another row of buttons, underneath rewind, minus, plus... Which would have actual speeds on them, so one could go from 2.0 to 0.75 or 1.25 with just one click.

EDIT: 09/06/2020
Issue has been fixed. 5 star extension, should be standard.

EDIT: 23/11/2017
Issue persists; check
https://sites.google.com/a/duneland.k12.in.us/sites-tutorial/add-a-calendar-to-your-site#TOC-EXAMPLE-CALENDARS

The full width and half width calendars fail to show up with the extension enabled, but work fine with it disabled. Blacklisting the websites works, but it's strange as to why this happens at all. Doesn't happen with the Chrome version of this extension.

Odd - prevents embedded Google Calendar from displaying properly. Otherwise, works on video websites.

Extension works as intended, however some keyboard keys are taken over by Firefox and thus can't be mapped to controls in this extension.

Props to active developer for reading comments.

Works on Android Firefox..stable version Nov 2017.

:)

it saves time

You can easily manage the video with this web tools.

i can watch faster now

its a good add on

Please put an option where you don't affect pitch when you change speed, sometimes i like to listen to song in lower pitch but I can't do it with this addon since it has pitch correction

I always wanted to be able to go faster than 2.0x on videos during the parts I already have seen or know. You can go as fast as you want with this tool. The best
