Is YouTube Downloader safe?

Low risk

YouTube Downloader Plus removes frame-blocking and content-security headers from every page response.

The extension registers a global web request listener that applies to both top-level pages and embedded frames on all websites. For each matching response, it removes X-Frame-Options and Content-Security-Policy headers before the browser receives them, which can allow pages to be framed or run with fewer site-defined restrictions.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 2 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.
