Video Downloader Plus 作者： devox

Video Downloader Plus helps you save videos from a wide range of websites directly in Firefox. When a video is playing on the page, the extension detects available streams and shows them in a simple popup so you can download the file you want.

How it works
1. Open a page with a video and start playback.
2. Click the Video Downloader Plus toolbar icon.
3. Choose a detected stream and download it, or use Record when direct download is not available.

Features
- Detects video streams automatically while you watch
- Shows useful details such as resolution, file size, duration, and format
- Direct download when the site exposes a downloadable stream
- Screen recording for live or protected content
- Works across many popular platforms

Supported sites include
Facebook, TikTok, Instagram, Vimeo, Twitter/X, and many other video sites.

Important notes
- YouTube is not supported.
- The video usually must be playing on the page before streams appear.
- On some sites, open the full video page (for example, a single TikTok or Instagram post) for best results.
- Some content may be protected and cannot be downloaded.
- Only download videos you have the right to save.
