The YouTube Repeat Button is a Firefox extension that introduces a much-needed repeat feature to the HTML5 YouTube player. This tool allows users to easily replay their favorite videos with a simple click. Upon installation, the repeat button is inactive by default, but it can be activated effortlessly. When enabled, the button changes color to white, and after a video ends, it briefly pauses before replaying the track from the start.

A significant update has introduced the capability to utilize the native loop function, improving the user experience by retaining the loop state even when switching tracks. Furthermore, the extension alerts users to switch to normal playing mode if the repeat button is pressed while in playlist mode. This extension is a practical solution for anyone looking to enhance their YouTube viewing experience.
