Most of the useful content today is created in the form of audio and video. The disadvantage of this is that it is more time consuming than reading. To make up the difference, use the “Video Speed Controller” extension.
Once you install it in your browser, you will see the speed slider in the corner of the video player when you open the video page. Just click the “+” and “-” buttons on the speed indicator to quickly increase and decrease the speed of the video.
If you don’t see the controls, you’re probably watching Flash video. You can also quickly control the recording speed with hotkeys. Use the expansion options to configure them.
