Is YouTube Downloader safe?

Low risk

YouTube Downloader strips X-Frame-Options and Content-Security-Policy headers from every page you load in Firefox.

A blocking webRequest listener removes the X-Frame-Options and Content-Security-Policy response headers from all main-frame and sub-frame loads on every http(s) site, not just the extension's own popup that loads app.veedmate.com. This weakens the framing and script protections those sites set for themselves. The extension also requests broad host, proxy and tab permissions.

Where it sends data

Destinations our analysis observed YouTube 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.

  • app.veedmate.com

    YouTube Downloader sends data to app.veedmate.com. No other extension we have analysed sends data here.
