DownXVideo - Twitter/X Video Downloader by kxnotes

DownXVideo adds a download button to every supported public Twitter/X video in Mozilla Firefox. Click the button to save that video as an MP4 without copying the post link or opening another downloader page.

• One button for each video in timelines and post pages.
• Supports single videos, multiple videos, GIFs delivered by X as MP4, and quoted posts.
• Choose the highest quality, a 1080p or 720p cap, or select a quality each time.
• Use readable filenames and keep quality, filename, and button preferences in local browser storage.
• Parses public posts with X syndication first and cookie-free X guest GraphQL only after a technical failure.
• Sends the source MP4 directly to the browser download manager; DownXVideo does not host or upload the video.

The extension does not read X cookies, login state, private messages, passwords, or account information. Only if both local parsing paths fail and you explicitly choose the website fallback is the public post URL sent to DownXVideo.

Use DownXVideo only for videos you own or have permission to save. DownXVideo is independent and is not affiliated with, endorsed by, or sponsored by X Corp. or Twitter.
