# Video Downloader for YT Companion for Windows

The Firefox add-on uses this local companion to discover formats and save media files. It runs
only on your PC and writes downloads to `Downloads\Video Downloader for YT` by default.

## Install

1. Extract this archive to a regular folder.
2. Double-click `install-helper.cmd`.
3. Restart Firefox.
4. Install the matching Video Downloader for YT add-on package.

The installer copies the companion to `%LOCALAPPDATA%\VideoDownloaderForYT` and registers the Firefox
native-messaging host for the current Windows user. Administrator rights are not required.

Run `install-helper.cmd --check` to validate the package without installing it. Run
`uninstall-helper.cmd` to remove the registered companion. Downloaded videos are not removed.

Save only content that you own or are authorized to download.
