Less Mixes for YouTube is a Firefox extension designed to enhance your YouTube viewing experience by preventing automatic mix playlists from being generated. This extension allows users to focus solely on the music videos or content they select, eliminating the frustration of unwanted mixes. It provides configurable options such as keeping music videos as standalone items, turning mixes into single videos, and playing only selected videos instead of starting the 'My Mix' playlist.

The extension works by clearing unnecessary URL parameters and redirecting users to a clean URL, ensuring that only the chosen video plays. It is compatible with all Chromium-based browsers and Firefox on various operating systems, including Windows, macOS, Linux, and now even Firefox on Android. Users should note that for optimal performance, YouTube must be opened in a new tab after the installation of the extension.
