Unsupported browser plugins found

The webpage in question leverages browser plugins that are not supported.

Why is this important?

Browser plugins are not commonly supported on mobile devices, and even desktop browsers tend to limit their functionality, leading to inaccessible content for a significant portion of users.

What does the Optimization check?

The Optimization will be activated for any URL that incorporates the following types of plugins:

  • Flash

  • Shockwave

  • Java applets

  • Director

  • Silverlight

Examples that trigger this Optimization:

An example would be a web page employing a Flash (.swf) object - such usage will set off the Optimization.

<object type="application/x-shockwave-flash" data="example.swf">  <!-- Display alternative content for non-enabled browsers -->  <div>    Flash content cannot be displayed  </div></object>

How do you resolve this issue?

The definite solution to this problem is to remove these outdated plugins or substitute them with contemporary, compatible alternatives, such as leveraging HTML5 for video playback instead of Flash.
