Is Download Facebook Videos safe?

Low risk

Download Facebook Videos rewrites Facebook and fbcdn request headers for requests started outside Facebook.

Its background webRequest handlers apply to facebook.com and fbcdn.net URLs. For non-Facebook initiators, the extension sets Facebook Origin and Referer headers, rewrites some Sec-Fetch headers, and changes CORS responses to allow access.

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.
