About Facebook Video Downloader
Facebook Video Downloader is a browser extension designed to help you save Facebook video content to your local device. It replaces the tedious process of using third-party converter websites by working directly in your browser.
When you visit a Facebook page with video content, the extension detects available streams. Click the extension icon to view your options, select a quality level, and the MP4 file downloads to your system.
Your videos are processed entirely within the browser. No media data leaves your device, no personal information is tracked, and the extension only activates on Facebook pages.
