100% Working YouTube Video Downloader Extensions [2025 Updatad]

Part 1: What Is YouTube Downloader Extension

A YouTube downloader extension is a browser add-on that allows users to download videos and audio directly from YouTube to their devices. These extensions integrate seamlessly into web browsers like Chrome, Firefox, Edge, and Opera, providing a straightforward way to save content for offline viewing with just a few clicks. These tools are particularly useful for users who want to watch videos or listen to music offline, save data, or use video/audio content for personal projects or educational purposes.

After extensive testing, we’ve identified just two YouTube download extensions that truly work. One noteworthy experience to share is our attempt with Video DownloadHelper on Firefox. While the extension does display a variety of video and audio formats, even 4K and 8K resolutions, the download button unfortunately didn’t function at all. Instead, it just aims to redirect us to download its software.
