About Enhancer for YouTube
Enhancer for YouTube is one of the oldest tools of its kind, from an independent developer who publishes as Max RF. It has over a million installs on Chrome and about 600,000 on Firefox, where Mozilla marks it Recommended. The pitch is straightforward: YouTube's player has few settings, so this adds them.
The core is playback. You can set a default speed and change it with the mouse wheel, from 0.07x to 16x, lock a preferred quality, boost volume and bass, and turn off 60fps formats. It adds cinema mode, a wide and mini player, a pop-up player, video filters, screenshots, custom themes and keyboard shortcuts. It can also hide end screens, comments, chat, Shorts and recommendations.
Two cautions. It is closed source under a proprietary licence, so unlike the three crowdsourced tools above you rely on the developer's word. Its history has a rough patch: in October 2023 the developer withdrew the Firefox listing, saying YouTube's changes had broken it, and it is listed again with a 2026 update. We found no paid tier or in-app purchase on its store listings. It suits people who watch a lot of YouTube and want the player tuned to their taste.
