Is Push to Kindle safe?

Clean risk

Push to Kindle sends the current tab URL and cleaned page HTML to pushtokindle.fivefilters.org when you click it.

When you click Push to Kindle, it injects a script into the active tab and copies the page document. It removes scripts, styles, canvas, select, and textarea elements, then posts the current URL and resulting HTML to the Push to Kindle service.

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.
