Missing Adobe Flash Player Plugin on Firefox 51
This section provides a tutorial example on what you will see on Firefox 51 with visiting a Web page that uses Flash without Adobe Flash Player Plugin installed.
What Is Adobe Flash Player Plugin? Adobe Flash Player Plugin is an add-on program for Firefox and other Netscape-compatible browsers that enables the browser to deliver multimedia information and interactivity programmed in SWF (Shockwave File).
If you do not have Adobe Flash Player Plugin installed and visit a Web site that uses the Flash technology with Firefox, you will get an error, or a prompt message to ask you to install it.
Without Adobe Flash Player installed, here is what I got on Firefox 51 with default settings:
1. Run Firefox 51 and visit the Adobe Flash Player test page at
http://herongyang.com/Flash/SWFC-ActionScript-Space-Explorer-Stabilized.html.
The test page will show an empty area with a missing plugin icon as shown below:
2. Read the error message below the missing plugin icon: "A plugin is needed to display this content."
Notice that unlike previous versions, Firefox 51 is not providing any links to allow you to install the Adobe Flash Plash Player plugin. This is because Adobe Flash is considered to be outdated and having high security risks. Firefox does not encourage you to visit Web sites that are using Flash content.
If you still want to view Adobe Flash content with Firefox, you need to download and install Adobe Flash Player plugin manually.
