Websites loading various web plugins such as Adobe Flash, Shockwave, Microsoft Silverlight, Java applets etc.
Historically, web plugins such as Adobe Flash, Java applets, Silverlight etc were used to deliver rich user experience to users in HTML-only browsers. As HTML5 support became more widespread offering the same experience but in standards-based manner, web browser vendors started to gradually end support for these plugins due to compatibility, maintenance and security concerns. In long-term website owners should thus plan to replace the plugin-based functionality with one based on HTML5 features.
