Is Flash Player safe?

Low risk

Flash Player Plus sends a persistent unique user ID and session timing data to flplayer.net on a recurring schedule.

The extension generates a random UID on first install and periodically contacts flplayer.net/config.php, transmitting the UID, the extension's runtime ID, and timestamps tracking how long the browser has been active. When playing Flash content over HTTPS, it routes the Flash file URL through greatapptst.com/redirect.php.
