Is Progressive Downloader safe?

Low risk

Progressive Downloader sends download URLs, referrers, and cookies to its downloader service.

When you send a link or matching browser download to Progressive Downloader, the extension reads cookies for that URL and packages them with the download URL and referrer. It first tries the native downloader host, then falls back to posting the same data to a local service on 127.0.0.1 ports 25300 through 25305 if native messaging is unavailable.

Where it sends data

Destinations our analysis observed Progressive Downloader contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
