TomasTNunes/TMDB-Player — reverse-engineered prompt

Build me a browser extension for TMDB that makes it easy to watch a movie or TV show from its TMDB page. When someone opens a movie or show page, the extension should quietly add a clear Play button next to the normal trailer button. When they click it, open a new tab with a simple player page that uses the TMDB title and id, and for TV shows also lets the person pick the season and episode.

The player page should let users choose between multiple streaming servers, and it should feel clean, simple, and not cluttered. Please make it work for Chromium browsers like Chrome, Edge, Brave, and Opera, and also Firefox if possible. Include the basic icons, permissions, installable extension files, and clear install instructions for manual loading. Keep the TMDB page looking normal except for the added Play button. Look up current browser extension docs online if you need to.
