9TSU Downloader

Designed to scan 9TSU video pages and identify embedded player sources along with any mirror links.

Will display available quality options complete with resolution details and estimated file sizes.

Intended to download direct video files or combine adaptive stream segments into a single MP4 file.

A progress panel is planned to show real-time speed, completion percentage, and estimated time remaining.

Built with automatic retry logic that picks up from the last segment if a connection drops.

Generates descriptive filenames based on the page title to help keep your library organized.

Runs entirely within your browser without using external servers or uploading your data.

Will support Chrome, Firefox, Edge, Brave, and Opera on Windows, macOS, and Linux systems.

Open a 9TSU video page and let the embedded player fully load so the extension can inspect it.

Clicking the extension icon follows iframes or mirror redirects and surfaces detected video sources with quality labels.

Select from available resolutions to fetch the video or stitch adaptive segments directly to your machine.

The finished MP4 saves to your downloads folder with a descriptive filename for offline playback.
