User reviews

Users appreciate the extension's ability to precisely control video speed and its simple, functional design. However, a significant issue affecting Amazon Prime Video causing black screens has been reported by multiple users. Performance degradation on Firefox, particularly with many tabs open, is another notable problem. The extension could benefit from more customizable controls and UI enhancements. Overall, it is useful but has notable compatibility and performance drawbacks.
Pros
  • Effectively controls video playback speed beyond default platform limits.
  • Simple and functional user interface.
  • Compatible with various video platforms including LinkedIn Learning and Prime Video (with some issues).
  • Basic permissions required are standard for similar extensions.
  • Has a blacklist feature to prevent performance issues on non-video websites.
Cons
  • Causes video playback issues on Amazon Prime Video (black screen) when enabled.
  • Performance degradation, especially with many open tabs, leading to browser slowdowns.
  • Lack of customizable hotkeys for additional controls.
  • User interface could be improved, such as opacity of controls and key bindings.

There is currently an issue where video playback does not display correctly on Amazon Prime Video. However, this is still an excellent plugin. The issue originates from the original Video Speed Controller by igrigorik, which this fork is based on. I believe that codebicycle will address it once the original is updated. In the meantime, the issue is being discussed in issue #1186 on igrigorik's GitHub, and a temporary workaround is known: ``` ▶️ While the video is playing, press V ✅ The controller overlay will be removed and video playback will resume as expected. ```

Since 2025-05-03, With this add-on, Amazon Prime Video can't work. I.e. Sound is OK. but Image is black screen. This problem happens on Chrome too. And it looks that other speed control add-ons don't have this problem. Please solve this problem.
