Features & Capabilities

Tired of squinting at small video thumbnails on the YouTube homepage? Dynamic Preview for YouTube™ upgrades your browsing experience by dynamically expanding video cards to give you a massive, cinematic preview—all without clicking or leaving the page!

Simply hover your mouse over any video on the YouTube home or channel page. Within a split second, that specific video card will elegantly expand to fill the entire row, allowing you to watch the automatic preview in high detail. The best part? The surrounding videos smoothly slide down to make room, keeping your grid perfectly organized with zero overlapping or annoying popups.

✨ Key Features: Full-Row Expansion: Hover over a video, and watch it seamlessly scale up to 100% of the row width for a massive, clear preview. Smart Grid Reflow: Unlike other zoom extensions that clip or overlap, this extension intelligently pushes other videos to the next row so nothing gets hidden. Seamless Playback: The default YouTube auto-preview continues to play flawlessly inside the enlarged card. Zero Clutter: No floating windows, no dark overlays, and no injected ads. Just a pure, clean YouTube experience. Easy Toggle: A simple, stylish popup menu lets you turn the extension ON or OFF instantly with a single click. Lightweight & Fast: Built with pure, optimized CSS and minimal JavaScript to ensure your browser remains lightning fast.

🛠 How to Use: Install the extension and pin it to your toolbar. Go to YouTube.com (refresh the page if you just installed it). Rest your mouse on any video thumbnail for 0.6 seconds. Enjoy the large, cinematic preview! Move your mouse away, and the grid snaps right back to normal.

Is Large Preview for YT Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Large Preview for YT requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious.

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
