Full Tab - Video & Iframe Maximizer

Full Tab

A browser extension that toggles videos or iframes to fill the entire browser tab.

How it Works

Click the extension icon while on any webpage and it will find the largest video or iframe and expand it to fill the entire browser tab. Click again to return to normal view.

Great for YouTube, embedded videos, or any site with iframes. Videos maintain their aspect ratio for a clean viewing experience.
