Is YouTube Video and Audio Downloader (WebEx) safe?
The extension downloads binaries from third-party GitHub repos without integrity verification and installs them via native messaging.
The extension downloads a native messaging host binary from the andy-portmen/native-client GitHub repository and an ffmpeg binary from the inbasic/ffmpeg GitHub repository. Neither download is verified with a hash or signature; the extension uses whatever URL the GitHub releases API returns. Once downloaded, the ffmpeg binary is placed in the user's home directory with execute permissions via a native messaging exec command.

Shared hosts - 1 hostname
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.
