Why TXXX Downloader
TXXX pages can expose different playback formats depending on the source and player state. Generic download tools often fail because they assume a single direct file instead of detecting the active stream after playback starts.
TXXX Downloader is built to make that process simpler. Open the page, let the extension detect the media, choose the available quality, and save the result as MP4 from inside the browser.
Features
- Detects supported TXXX video streams from multiple sources
- Lists available quality variants when present
- In-page download button built into the video player
- Converts HLS streams to downloadable MP4 files in-browser
- Right-click context menu for a faster download flow
- Real-time progress tracking with download speed and file size
- Desktop notifications when downloads complete
- Auto-saves to an organized TXXX subfolder in Downloads
- Saves output as MP4 for broad compatibility
- Cross-browser support for Chrome, Edge, Brave, Opera, Firefox, Whale, and Yandex
How It Works
- Install the extension from the latest release.
- Open a TXXX video page and press play.
- Let the extension detect the media source.
- Open the popup or use the in-page download button.
- Choose the quality or stream option you want.
- Start the download and wait for the MP4 export to finish.
- Save the final MP4 file locally.
Step-by-Step Tutorial: How to Download Videos from TXXX
- Install TXXX Downloader from the latest GitHub release.
- Open TXXX and sign in if the page requires account access.
- Navigate to the video page you want to keep.
- Let the player load fully and press play.
- Click the in-page download button on the player or open the extension popup.
- Review the quality options shown by the extension.
- Choose the resolution you want if multiple options are shown.
- Start the download and wait for the MP4 export to finish.
- Open the saved video from your Downloads folder.
Supported Formats
- Input: supported TXXX watch-page sources (flashvars, HTML5 video, CDN)
- Input: TXXX HLS streams
- Output: MP4
Saved files use MP4 so they are easier to replay on standard media players, transfer between devices, or archive for later access.
Who It's For
- TXXX viewers who want offline copies of supported videos
- Users who need a simpler alternative to manual extraction
- People archiving videos they are allowed to access
- Browser users who do not want extra desktop tooling
- Anyone who wants a browser-based workflow instead of command-line tools
Common Use Cases
- Save a supported TXXX video for later
- Export the highest available quality as MP4
- Avoid manual URL hunting in page scripts
- Keep local copies for offline playback
- Download the best quality exposed by the page
Troubleshooting
The extension is not detecting anything Press play first and wait for the player to finish loading.
The listed source looks wrong Refresh the page and retry after starting playback again.
Only one quality is available That means the page currently exposes only one usable source.
The download stopped or failed partway through Check whether your internet connection dropped during the export. Retry the download from the popup.
