Loopify

This extension makes it simple to loop specific sections of any YouTube video. Instead of dragging the progress bar or clicking replay repeatedly, you can just pick a start and end time and let the extension replay that portion automatically. If you want to repeat more than one part of a video, you can add as many segments as you like, and the extension will move seamlessly from one segment to the next. There’s a small button in the YouTube player’s control bar—click it to open a panel where you can set up your loops, enable or disable them, and save your settings for each video. For quick access, you can press Ctrl+L at any time to open or close the looping panel. It’s perfect for learning new skills, studying tutorials, practicing sections of songs, or simply rewatching the best parts of your favorite videos.
