Private Video Downloader is a Firefox extension designed for efficient video downloading while prioritizing user privacy. This tool enables users to download videos from various websites directly to their computer in multiple formats such as MP4 and WEBM. Its user-friendly interface allows for simple operation: users can visit a video page, click the extension icon, and select the desired video file for download. The extension stands out by managing browsing history, ensuring that entries from designated 'private' sites do not clutter the user's history.

The main feature of Private Video Downloader is its automatic privacy management, which removes history entries for specified sites, eliminating the need for incognito browsing. However, it is important to note that the extension cannot download videos from YouTube and may not support protected videos that utilize certain protocols. Additionally, it requires various permissions to access browsing and download history to provide its full functionality.
