If you need to alter the speed at which HTML5 video elements play on a webpage, there's a simple solution available in the form of an extension or add-on. Using Video Speed Control for Chrome, Firefox, and Edge is easy - all you have to do is start playing the video you want to adjust and then open the toolbar popup UI to access the playback speed controls. Once you've made the necessary adjustments, click the green check mark button to apply the changes.

It's essential to keep in mind that you will need to repeat this process every time the page is reloaded, or the playback speed is modified. Additionally, the minimum speed allowed is 0.07x, and the maximum speed is 16x, which complies with HTML5 standards.

If you're looking for a lightweight and user-friendly option to modify video playback speed, Video Speed Control for Chrome, Firefox, and Edge is an excellent choice. This add-on/extension allows you to change playback speed from your browser's toolbar popup conveniently.
