TabScreen

Keeps video/player fullscreen inside the browser viewport instead of taking over the entire display.

TabScreen gives video fullscreen a calmer, more useful shape. Instead of letting a video player take over your entire display, TabScreen keeps fullscreen contained inside the browser viewport. You still get the focused, edge-to-edge player experience, but Chrome stays out of system fullscreen mode. It is built for people who watch videos while working across apps, monitors, tabs, calls, notes, dashboards, or anything else that should remain accessible. Features: - Keeps video fullscreen inside the browser window - Works automatically when a player requests fullscreen - Supports regular video elements and iframe-based players - Preserves the player’s own controls and layout whenever possible - Designed to work well with YouTube and other modern web players - Lightweight, no account, no tracking, no setup - TabScreen is especially useful when you want a video to fill the tab without hiding your operating system, switching display modes, or breaking your desktop workflow. Install it, click fullscreen as usual, and keep the video where it belongs: inside the tab.
