Is YouTube Video Downloader safe?

Low risk

YouTube Video Downloader removes frame and content-security headers from every page and iframe response.

When pages or embedded frames load, the extension intercepts response headers for all URLs and removes X-Frame-Options and Content-Security-Policy before the browser receives them. This can let sites be embedded in frames or run without CSP restrictions that the site intended.

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.
