Video Fullscreen Helper

Force the current tab's video to fill the browser window or the whole screen — even when the site's own web fullscreen is broken.

Many video sites ship a broken "web fullscreen" button — the video only goes properly fullscreen. Video Fullscreen Helper fixes this by forcing the video in the current tab to fill the window itself. TWO MODES • Web fullscreen — the video fills the entire browser window, while the browser stays windowed (taskbar and other windows remain visible) • Full fullscreen — the browser enters fullscreen mode and the video fills the whole screen WHY IT WORKS WHEN THE SITE'S OWN BUTTON DOESN'T • Applies forced inline styles to the player container, the <video> element, or the embedded iframe — no reliance on site CSS • Anti-occlusion: site headers, sidebars, floating widgets and dialogs that would cover the video are detected and handled automatically • Adapts when the site rewrites its layout, replaces the video element (e.g. quality switching) or pops up new overlays mid-playback • Everything is snapshotted on entry and fully restored on exit — no traces left behind USAGE • Click the toolbar icon and choose a mode; the popup closes automatically on success • Press Esc in the page to exit (full fullscreen also restores the browser window to its previous state) • Optional: show the browser's native video controls, or stretch the video to fill the window • Keyboard shortcuts are unbound by default — set them at chrome://extensions/shortcuts PRIVACY This extension does not collect, transmit or sell any data.
