Whenever a user enables a plug-in on a website, it’ll remain enabled as long as the user regularly visits the website and and website still uses the plug-in. All of the settings controlling what plug-ins are visible to web pages and which ones are automatically activated can be found in Safari’s Security preferences. Safari 10 also includes a menu command to reload a page with installed plug-ins activated it’s in Safari’s View menu and the contextual menu for the Smart Search Field’s reload button. Here too, the default option is to activate the plug-in only once. When that’s clicked, Safari offers the user the options of activating the plug-in just one time or every time the user visits that website. When a website directly embeds a visible plug-in object, Safari instead presents a placeholder element with a “Click to use” button. We have similar handling for the other common plug-ins. The default option is to activate it only once.
If a user clicks on one of those links, Safari will inform them that the plug-in is already installed and offer to activate it just one time or every time the website is visited.

Most websites that detect that Flash isn’t available, but don’t have an HTML5 fallback, display a “Flash isn’t installed” message with a link to download Flash from Adobe. Of these plug-ins, the most widely-used is Flash. This convinces websites with both plug-in and HTML5-based media implementations to use their HTML5 implementation.
It does this by not including information about Flash, Java, Silverlight, and QuickTime in ugins and navigator.mimeTypes. How This Worksīy default, Safari no longer tells websites that common plug-ins are installed. The rest of this post explains the implementation of this policy and touches on ways to reduce a website’s dependence on legacy plug-ins. If you’re a web developer, you should be aware of how this change will affect your users’ experiences if parts of your websites rely on legacy plug-ins. If a website really does require a legacy plug-in, users can explicitly activate it on that website. This policy and its benefits apply equally to all websites Safari has no built-in list of exceptions. On websites that offer both Flash and HTML5 implementations of content, Safari users will now always experience the modern HTML5 implementation, delivering improved performance and battery life. When Safari 10 ships this fall, by default, Safari will behave as though common legacy plug-ins on users’ Macs are not installed. These standards now include most of the functionality needed to support rich media and interactive experiences that used to require legacy plug-ins like Adobe Flash. The WebKit project in particular emphasizes security, performance, and battery life when evaluating and implementing web standards. Thanks to the ongoing hard work of standards bodies, browser vendors, and web developers, web standards are feature-rich and continuously improving. The web platform is capable of amazing things. These changes may affect compatibility with your websites. This is a guest post from the Safari team about changes to how Safari allows WebKit to use plug-ins.
