YouTube Fast Forward & Rewind is a Firefox add-on designed to improve video playback on YouTube by allowing users to add custom skip buttons and configure keyboard shortcuts for more precise seeking. This tool enhances user interaction with the platform by providing features such as custom skip times for the left and right arrow keys, which can override YouTube's default settings. An on-screen skip indicator appears during use, displaying the exact amount of time skipped, complemented by smooth animations for a better user experience.

The add-on also includes a statistics panel that tracks total skips, ensuring that all data remains private and stored locally on the user's computer. Users can adjust player responsiveness with action delay control and benefit from integrated controls that blend seamlessly into YouTube's interface. With auto-save functionality for custom settings, YouTube Fast Forward & Rewind offers a tailored navigation experience for those looking to optimize their video playback.
