Extension Metadata

About this extension
Pop any web video into a floating, resizable frame. Drag, resize, dim the page, go fullscreen, and control playback from the keyboard.

Full description:

Watch videos your way, on any website.

Media Frame Resizer lifts the video out of the page and puts it in a clean, floating frame you can move and resize freely. The site’s own controls, overlays and clutter stay behind. You get just the video, with a simple control bar of your own.

Resize and position
• Drag the frame anywhere and resize it from any edge or corner
• One-click sizes: Picture-in-Picture corner, 50%, 75%, or fill the whole tab
• Lock the aspect ratio, or hold Shift while resizing to adjust it freely
• Remembers your preferred size and position for each website

Built-in player controls
• Play/pause, jump back or forward 10 seconds, seek bar, volume, and playback speed (0.25× to 2×)
• Live streams show a LIVE indicator and how far behind live you are
• Controls fade away while the video plays and reappear when you move the mouse

Keyboard shortcuts
• Alt+Shift+M: open or close the frame
• Space or K: play/pause
• ← → or J L: back or forward 10 seconds
• ↑ ↓: volume
• M: mute
• < >: slower or faster
• F: fullscreen
• Esc: put the video back where it was

Theater mode and fullscreen
• Dim the rest of the page to focus on the video
• Fullscreen keeps your controls available, with no scrollbars or clutter

Works where other tools don’t
• Handles embedded players, including videos inside iframes and modern web-component players
• Stays on top of sticky headers, chat widgets and pop-ups
• Close the frame and the page goes back exactly as it was
