Add keyboard shortcuts that will increase/decrease the playback rate for video elements.
目前為
Updated version of the old video-element-rate-controller, with some added enhancements, such as syncing the playback speed with the Enhancer for YouTube extension, as well as being optimized to have a lower memory footprint.
By default, "[" will slowdown by 0.1x and "]" will speedup by 0.1x. This speed value can now be adjusted in the configuration menu for the script. Let me know if you have problems now that localStorage is being used.
In the future, I may make the key that changes the speed to be configurable.
Tested working with Mozilla Firefox 62.0b12 (32-bit) and Mozilla Firefox 61.0.2 (64-bit).
