Picture in Picture 作成者: Alanas

Pop any video out of the page. One click on the toolbar icon, or press Alt+P. The video floats in its own window while you switch tabs, take notes, or read.

What it does:
Finds the largest visible HTML5 video element on the active tab and calls requestPictureInPicture() on it. Click again to put the video back. The standard Picture-in-Picture API is built into Firefox; this extension just adds a one-click toolbar entry point that also works inside iframes.

Features:
- One click toggles Picture in Picture on the largest visible video.
- Alt+P keyboard shortcut.
- Small "PiP" badge when a video from this tab is floating.
- Works inside iframes where Firefox's own PiP button does not appear.
- Plain-English notification when a site blocks PiP.
