Safari 5.1.7 disables out-of-date versions of Adobe Flash Player. Out-of-date versions of Adobe Flash Player don’t include the latest security updates and will be disabled to help keep your Mac secure, according to Apple. If Safari 5.1.7 detects an out-of-date version of Flash Player on your system, you’ll see a dialog informing you that Flash Player has been disabled. The dialog provides the option to go directly to Adobe’s website, where you can download and install an updated version of Flash Player.
