Comet - Reddit Comments on YouTube is a browser extension for Firefox that enhances the user experience on YouTube by integrating comments from Reddit. This innovative tool replaces the standard YouTube comment section with discussions from corresponding Reddit threads, providing users with a broader perspective on video content. Users can still access YouTube comments via an icon, allowing for a seamless transition between platforms.

The extension features a simple popup interface that reveals the relevant Reddit post and its comments, making it easy to engage with community discussions. Comet operates on a subscription model, ensuring an ad-free experience while prioritizing user privacy by not collecting data or requiring signups. This tool is ideal for users seeking deeper conversations beyond the YouTube comments.
