Firefox Note

FastStream is a browser extension that replaces videos on websites with its own video player. It pre-buffers video in the background and uses parallel requests, and offers subtitle features, audio and video adjustments, and remappable keybinds. It supports MP4, HLS and DASH streams. Livestreams and DRM-protected content are not supported, and the player is described as a work in progress.
