Easily control HTML5 video playback speed via toolbar popup
Video Speed Control extension lets you easily control the playback speed for all HTML5 video elements.
To work with this add-on, please open a webpage that contains HTML5 video elements. Then, play the desired video element and open the toolbar popup UI. Within the UI, adjust the playback speed and then click on the - Play - button (footer section). The playback speed will be changed according to the value shown in the popup. Please note that this add-on does NOT change the speed automatically. You need to open the toolbar popup UI and press the - Play - button each time (needs user-action). Moreover, every time a page is reloaded, the add-on needs a user action again. The minimum playback speed is 0.07x and the maximum speed is 16x. The min and max values are according to the HTML5 standards.
If you have a feature request or found a bug to report, please fill the bug report form on the add-on's homepage (https://mybrowseraddon.com/video-speed-control.html).
