About this extension
Companion extension for Galactic Downloader, a free, open-source download manager for Windows 10 and 11. It needs the app, from https://github.com/xoGUYFAWKSxo/internet-downloader/releases
  • Spots video and audio files and HLS/DASH streams on the pages you visit, and lists them in its popup with a plain description, such as "Video with sound · up to 1080p".
  • Sends the one you choose to the app, with the cookies and headers the site needs, so downloads that need a sign-in work.
  • Adds "Download this with Galactic Downloader" to the right-click menu on videos and audio, "Download link with Galactic Downloader" on links, and "Download the playing video with Galactic Downloader" on pages where it has found a video.
  • Hands files of 1 MB and larger that the browser starts downloading to the app instead. If the app can't download one, the browser carries on. This can be turned off in the popup.

The app downloads over several connections at once, resumes after a dropped connection, and joins separate video and sound into one file. Copy-protected (DRM) streams are not supported.

Nothing is sent to the developer or any server: the extension talks only to the app on your computer. Source code and privacy policy: https://github.com/xoGUYFAWKSxo/internet-downloader
Developer comments
This extension needs the Galactic Downloader app (free, Windows 10 and 11). Install it first from the releases page; no admin rights needed. Without the app, the extension can't download anything.

To check it's working: click the extension's icon, then Check connection to the app. It shows the app's version.

Good to know:
- Copy-protected (DRM) videos are refused, such as Netflix, Disney+ and other paid streaming services.
- YouTube's own player isn't supported.
- Nothing is sent to the developer: the extension talks only to the app on your computer.
