This document describes a problem that is encountered when Show and Share is used in order to view video content and provides a solution to the problem.
In order to play Flash, Windows Media Video (WMV), or MP4 content via Show and Share, your browser might require that a plugin be installed. In some cases, Show and Share might have multiple formats of a single video. If the browser requires a plugin that is not installed (or enabled), it might revert to an alternate version. It is in this scenario that you might experience the problem that is described in this document.
When you attempt to view an internal Show and Share video, a plugin alert pops up, but the video plays in the background:
An inspection of the source for this popup element reveals that the requested plugin is for Windows Media Player (application/x-ms-wmp).
With Mozilla Firefox Versions 21 and later, scans of the <installation directory>/plugins folder are no longer run by default.
Complete these steps in order to resolve this issue:
- Enter about:config into the Location bar and press Enter.
- Search for plugins.load_appdir_plugins.
- Double-click plugins.load_appdir_plugins in order to change the value to True.
- At the top of the browser window, click the Firefox button and select Exit. When you restart the browser, the plugins are enabled.
After you restart the browser, the plugin alert should not appear. If it does, then you might not have the Windows Media Player plugin installed on your system. Follow the instructions that are given in the Checking if the plugin is installed section of the Play Windows Media files in Firefox with the Windows Media plugin Mozilla Support document.
