Safari users with security concerns usually open Preferences, click on the Security button, and adjust a few settings.
For example, more technical Mac users will turn off the Enable Java checkbox. Others will want to turn on the Warn When Visiting A Fraudulent Website button.
There’s even control over referrer headers to prevent them from being sent to websites. You can also check on the actual URL of a short URL so you’ll know where Safari is being pointed.
Remember, a little paranoia goes a long way when it comes to security and a safer browsing experience.
