Still blocks animated images and motion effects in Safari, giving you a calm, static browsing experience.
What it blocks:
• Animated GIFs — replaced with a static placeholder. Includes GIFs served via image-proxy URLs (Next.js, Cloudinary) and cross-origin CDNs that often slip past simpler blockers
• Animated WebP and APNG — detected by inspecting file headers; static images display normally. Catches APNGs served with a .png extension, animated AVIFs, and animated SVGs loaded as images
• Animated canvas backdrops — WebGL shader and generative-art animations, the kind of full-page motion no image blocker can touch, are frozen on a still frame. Static canvas charts render normally
• Inline video product previews used as animated-image substitutes — Google Shopping's spinning 3D product cards and similar muted, autoplaying clips that bypass Safari's autoplay control
• CSS transitions that create subliminal smooth motion (carousel crossfades, opacity pulses, sliding banners)
• CSS background-image animations
• SVG animations
• JavaScript-driven page-load flourishes — jQuery `.animate` sweep effects, "curtain bar" reveals, and similar attention-grabbing intros
• Animations inside embedded frames (ads, social embeds) — covered by the same rules as the main page
• Per-site rule pack — sites with known animation patterns (e.g. president.mit.edu's hero curtain) get tailored protection without breaking the rest of the page
What it doesn't break:
• Static images (JPEG, PNG, SVG, WebP) display normally
• Canvas apps you actually use — games, maps, drawing tools — stay fully interactive; a click or keypress hands the canvas back to you
• Videos you start yourself keep playing; only autoplay-style motion is stopped
• Page layout and functionality are preserved — replacements never shift the page
• Per-site allowlist lets you enable animations on sites you trust
• Global on/off toggle in the extension popup
