Is Save-Data: on safe?

Clean risk

Adds a Save-Data: on header to web requests so sites can reduce downloaded content when they support it.

This extension tells websites that you prefer to save data by sending the Save-Data: on HTTP header with every request. Websites may choose to respond with lower-quality images or fewer media elements to reduce downloads. It is not a data compression proxy.

What this publisher told the store about itself, and the other listings that told it the same thing.

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.
