Is Sprint — YouTube Speed Booster safe?

Clean risk

Sprint - YouTube Speed Booster routes configured YouTube media domains through Sprint proxy servers.

When it starts or connects, the extension fetches proxy connection details from speedyext.ru and applies browser proxy settings for YouTube-related domains such as youtube.com, googlevideo.com, ytimg.com, and youtu.be. Matching YouTube requests are sent through the returned proxy host and port, so YouTube URLs and request headers can pass through Sprint's proxy path.

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.
