The procedure is the same for other common plug-ins, according to Mondello.
The default option will be to activate it only once. When a user clicks on one of the links, Safari will advise them that the plug-in is already installed and allow them to activate it just one time or every time the website is visited. “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,” he added.įor most websites that detect that Flash isn’t available, but don’t have an HTML5 fallback, a message that “Flash isn’t installed” will be displayed with a link to download Flash from Adobe.
