Safari 10 Will No Longer Load Legacy Plugins By Default

Ricky Mondello, on the WebKit blog:

By default, Safari no longer tells websites that common plug-ins are installed. It does this by not including information about Flash, Java, Silverlight, and QuickTime in navigator.plugins and navigator.mimeTypes. This convinces websites with both plug-in and HTML5-based media implementations to use their HTML5 implementation.

Of these plug-ins, the most widely-used is Flash. 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. 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. The default option is to activate it only once. We have similar handling for the other common plug-ins.

The worst is when a site that could serve you HTML5 media content instead sends you the Flash version, just because you have Flash installed. This should fix that problem for Safari users.
