About this extension
🚀 HOW TO USE (Quick 3-step setup):
1. Install this Firefox extension.
2. Download & install the free Windows companion app: https://yt-grab-2df.pages.dev/
3. Open any YouTube video or Short, click "Download", and choose your quality!
✨ Features:
• 1-Click Download: A clean download button right under YouTube videos and Shorts.
• Multi-Quality Menu: Choose between 4K / Best Quality, 1080p Full HD, 720p HD, or Audio Only (MP3 / AAC).
• Direct to Downloads: Saves directly into your PC's standard Downloads folder.
• 100% Free & Open Source: No subscriptions, no ads, no trackers, and no malware.
💡 Why the companion app?
Modern YouTube serves 1080p and 4K video streams separately from audio. Standard browser extensions cannot merge these streams without crashing or throttling speeds. The lightweight companion app uses yt-dlp & FFmpeg to ensure ultra-fast, unrestricted downloads with full sound.
