Sometimes, the video or audio content in a web page cannot be properly downloaded and displayed in Firefox. A required plugin may be missing, outdated, blocked, in conflict with another plugin or extension, or the content may be blocked for some reason. This article will help you solve these problems.
If you have more than one plugin installed that can handle the same media type, this can cause a conflict that prevents some embedded media from playing. You may be able to fix the issue by disabling one of the plugins.
At the top of the Firefox window, click on the Firefox button, and then click Add-ons. The Add-ons Manager tab will open.
- In the Add-ons Manager tab, select the Plugins panel.
- In the list of plugins, select the plugin you wish to troubleshoot.
- If you want to disable the plugin, click the Disable button.
- If you want to re-enable the plugin, click the Enable button
For example, you may need to disable the VLC plugin to play embedded QuickTime or Windows Media content.
