    Version 1.4.0

    Released Nov 14, 2026 - 103.65 KB
    Works with firefox 140.0 and later
    New quality for animation: Anime4K. It cleans up compression artifacts and blur, then redraws the lines at higher resolution. Choose it from the popup or with Alt+Shift+G; it needs a capable GPU, and falls back to FSR 1 when the GPU cannot keep up
