Some websites use plug-ins to provide video, animation, or other special content. Common examples include Adobe Flash Player, QuickTime, and Oracle Java. However, plug-ins can be exploited and may present a security or privacy risk. You can choose to use only certain plug-ins on trusted websites you select.
A dialog may appear when you visit a website that has plug-in content or when you change the blocking policy for a plug-in in the Security pane of Safari preferences.
If the dialog asks you to trust the website and the plug-in content is visible, you have these choices:
Trust: Safari uses the plug-in to show content for this website and doesn’t ask about this plug-in when you visit this website again.
Cancel: Safari shows a “[Plug-in] blocked for this website” placeholder instead of plug-in content on this website now and when you visit it again. To see plug-in content, click the placeholder, then click Trust.
If the dialog asks you to trust the website and the plug-in content isn’t visible, you have these choices:
Never for this Website: Safari doesn’t let the website use the plug-in.
Trust: Safari lets the website use the plug-in and doesn’t ask about it when you visit this website again.
Not Now: Safari doesn’t let the website use the plug-in now, but asks about it again the next time you visit this website.
If you’re changing a plug-in’s blocking policy to Run in Unsafe Mode, a dialog gives you these choices:
Trust: Safari uses the plug-in in unsafe mode. The plug-in can access your personal data and documents.
Cancel: Safari doesn’t use the plug-in in unsafe mode. When a plug-in runs in unsafe mode, it can access your personal documents and data.
If the dialog says a plug-in needs updating, you have these choices:
Download [Plug-in]: Goes to a website where you can get an update. After downloading, install the update, then quit and reopen Safari.
OK: Safari shows a “[Plug-in] out-of-date” placeholder instead of plug-in content on this website until you update the plug-in.
To see plug-in content, click the placeholder, click Download [Plug-in], install the update, then quit and reopen Safari.
If the dialog says your plug-in version has critical security issues, Safari doesn’t let the website use the plug-in.
To let the website use the plug-in anyway, choose Safari > Preferences, click Security, then click Website Settings next to Allow Plug-ins. In the settings dialog for website plug-ins, select the type of plug-in on the left, click the pop-up menu for this website, then choose Allow Always. Choosing Allow Always may present a security or privacy risk, so only choose this option for a website you trust.
To change the plug-in blocking policy for future visits to a website, choose Safari > Preferences, click Security, then click Website Settings next to Allow Plug-ins. For more information about the policy options, see Security pane of Safari preferences.
