Video Speed Controller is described as 'HTML5 video provides native APIs to accelerate playback of any video, but most implemented players either hide or limit this functionality. This extension fixes that, plus more'. There are three alternatives to Video Speed Controller for Google Chrome, Windows, Online / Web-based, Chrome OS and Firefox. The best alternative is Faster Video, which is free. Other great apps like Video Speed Controller are Video Speed Controller with Hotkeys (Free) and HTML5 Video Speed Control (Free).
Faster Video for Firefox for Desktop that allows one to manipulate the playback rate of HTML5 videos. While right-clicking on a video allows one to change the playback rate to either 1.5X or 2.0X, this addon gives more control.
Video speed controller chrome extensions have overly complicated functionalities and settings. All people want to do is speed up their videos! So this version only has 5 hotkeys -- Shift + up/down/left/right and enter for different speeds. Enjoy!.
