Safari 6/7 (Mavericks): If features on a webpage don’t work
If features of a webpage don’t work, utilities that help Safari handle special content may be turned off.
- Choose Safari > Preferences, then click Security.
- Make sure this checkbox isn’t selected: “Block pop-up windows.”
If the features still don’t work, you may need a plug-in. Look for a placeholder on the webpage, such as “__ blocked for this website,” then click it for more information.
