Is MagicalDownloader safe?

Low risk

MagicalDownloader lets any HTTP(S) page send media URLs to its background downloader through a page-message bridge.

Its content script runs on every HTTP and HTTPS page and accepts window messages without checking the page origin. A page can pass a URL, referrer, and file type into the extension, and when auto-download is enabled for that tab the background script downloads the supplied URL through the browser.

Shared hosts - 3 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
