Faster Video is described as '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'. There are three alternatives to Faster Video for a variety of platforms, including Google Chrome, Windows, Chrome OS, Firefox and Linux. The best alternative is Video Speed Controller, which is both free and Open Source. Other great apps like Faster Video are HTML5 Video Speed Control (Free) and Video Speed Controller with Hotkeys (Free).
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!.
