When you want to control the playback speed of videos.
Solutions
Browser controls
Your browser may allow you to control playback speed of videos. Firefox and Microsoft Edge provide this option as of August 2020, although browsers are evolving constantly. For many browsers, if you right-click on a video you will be presented with the options available.
Downloading videos
If you can download media as an option to watching it as embedded on a webpage, you can use the player of your choice to view it.
