bfbnagnphiehemkdgmmficmjfddgfhpl

Remove black bars and fit any video to your screen. Works on Netflix, YouTube, Prime, Disney+, HBO and all video sites. Remove black bars from any video. Fit any video to your entire screen on any video platform — automatically. UltraWideo is the cross-browser extension that manipulates video aspect ratio to fill your screen. Whether you own an ultrawide monitor (21:9, 32:9), a standard 16:9 display watching 4:3 videos, or anything in between — UltraWideo eliminates black bars and gives you a true full-screen experience. Why UltraWideo over other extensions? Unlike alternatives that break on certain platforms or stop detecting videos, UltraWideo is proven to work on all major video streaming platforms, including embedded videos across the web. No "video not detected" errors. No broken layouts on non-video pages. It only activates when there's a video to work with. ▸ Works everywhere — any streaming service, any site with embedded video, any platform. Not limited to a single site. ▸ Blazingly fast — written in plain JavaScript with a tiny footprint. No memory leaks, no background processes draining your battery, no performance degradation over time. ▸ Minimal interface — a thoughtful popup that doesn't get in your way. No intrusive overlays, no UI that pops up over your video. Just clean controls when you need them. ▸ Multiple modes — Upscale to fill your screen, Stretch to fit, or scale manually. One mode active at a time for a simple experience. ▸ Adjustable scale — fine-tune the zoom level to get exactly the crop you want, simultaneously with the active mode. ▸ Magic touch — toggle between modes using pinch gestures on trackpads and touch screens, or mouse wheel + CTRL key. No other extension offers this. ▸ Keyboard shortcuts — fully customizable through your browser's built-in shortcut manager, so they never conflict with other extensions or websites. ▸ Dark & light mode — automatically matches your system appearance, or set it manually. ▸ Cross-browser — available for Chrome, Firefox, Edge, and all Chromium and Gecko-based browsers. ▸ 40+ languages — AI-translated for global accessibility. Pro Features Support UltraWideo's development and unlock bonus features: ▸ Magnetic Helper — make UltraWideo work outside of fullscreen by attaching it to any video player you select. Perfect for windowed viewing. ▸ Accent Color — personalize the interface with 8 carefully selected color themes. ▸ Disabled Mode — hide modes you don't use for faster switching. ▸ Consents — control which notifications you receive. ▸ Ambient Light — adds an immersive ambient glow around your video, enhancing the viewing experience and helping protect OLED screens from uneven burn-in. Trusted by 75,000+ users across Chrome and Firefox. Works on any screen size and any aspect ratio. If it doesn't work somewhere, open a ticket on GitHub and it will be fixed.
