## Description

🔊 Volume Booster — Firefox Extension
<blockquote>Push your browser audio beyond the default 100% limit — up to 500% — using the Web Audio API.</blockquote>
Firefox caps webpage volume at 100% natively. Volume Booster breaks that ceiling by routing all audio and video elements through a <code>GainNode</code>, letting you crank quiet tabs, videos, or music players to levels that are actually audible. It works on YouTube, Spotify Web, SoundCloud, and any other site that uses HTML5 <code>&lt;audio&gt;</code> or <code>&lt;video&gt;</code> elements.

✨ Features
<ul><li>🎚️ <strong>Volume slider from 100% to 500%</strong> — smooth gain control beyond the browser default</li><li>🔁 <strong>Live updates</strong> — changes apply instantly without reloading the page</li><li>👁️ <strong>Works on dynamic pages</strong> — a <code>MutationObserver</code> catches media loaded after the page opens (e.g. YouTube)</li></ul>
