DLSS Anything by zabusa2007

⚠ This add-on needs a free companion app on your computer. It does nothing without it. After you add DLSS Anything to Firefox, a setup page opens: download the companion app for Mac or Windows, double-click its installer, and the page turns green.

DLSS Anything plays a neural-rendered version of the video you are watching, laid exactly over YouTube's or Plex's own player and kept in sync with it frame by frame. Audio and controls stay the site's own. Where nothing is rendered yet, you see the original.

The rendering happens in the open-source companion app, not in the browser. It works on:

• Windows with a GeForce RTX 50 series GPU, through the community DLSS 5 Video Player runtime;
• Apple Silicon Macs (macOS 26+), through MLX-DLSS.

Any other computer can try every feature in simulated mode (a labelled stand-in filter, not DLSS 5).

The DLSS 5 runtime and model are not included and must be obtained separately under their own terms.

Features

• Strength: blend the render over the original, instantly.
• Look: the DLSS 5 controls games expose (intensity, local structure, colour, tone, skin), plus the Natural, Detail only, Gentle and Strong presets.
• Performance presets: a low-resolution neural pass followed by an upscale ("Neural Upstream"), and 30 fps rendering for 60 fps video.
• Wait for DLSS: pauses while the render catches up, on slower GPUs.
• Compare: DLSS 5, split screen or original.
• YouTube and Plex Web, including self-hosted Plex servers.

Privacy: nothing leaves your computer through the add-on. It talks only to the companion app on 127.0.0.1.
