Tab Fullscreen Video - Windowed Fullscreen

Fullscreen any Video within your browser tab.

This Chrome extension enables a tab fullscreen (also known as windowed fullscreen) mode for Videos on almost any website. Just press the "f" key while a video is playing, and it will expand to fill your browser tab using a custom overlay — no native fullscreen required. Works on: YouTube, Twitch, Udemy, Linkedin, Vimeo, Instagram, Reddit, Twitter/X, TikTok, Dailymotion, PlutoTV, and most standard HTML5 players. Features: • Fullscreen inside your current tab • Avoids native fullscreen interruptions • Fast keyboard toggle (press f) • Lightweight, secure, and private PERMISSIONS EXPLANATION: This extension requires access to all HTTPS websites because it provides universal video fullscreen functionality. We cannot predict which sites contain videos or what custom video players users will encounter. Your privacy is protected: • No data is collected or transmitted • No remote code execution • Only HTTPS sites (more secure) • Extension only activates when you press 'f' on video content
