While you are surfing the Internet with the Firefox browser, you may encounter some websites that require a media player plugin in order to play media embedded in their pages. You can use the VLC Media Player plugin to play embedded media files. However, after installing the plugin in Firefox, you must enable it before you can use it. The option to enable a plugin in Firefox is located in the "Plugins" settings.
Launch the Firefox browser and go to the VLC Media Player download page.
Click the "Download" button, and then click "Save Files" on the pop-up window. The Downloads pop-up window automatically opens.
Double-click the "VLC" file in the Download list, and then click "Run" on the pop-up window. The VLC Media Player installation wizard opens.
Follow the instructions from the wizard to install the player. For example, click the "Mozilla Plugin" check box to install the player in Firefox. Click "Finish" when the installation is complete. The VLC plugin is automatically added to Firefox.
Launch Firefox, and then click the "Firefox" button on the top-left corner of the window.
Click "Add-ons" in the drop-down list. The Add-ons window opens.
Click the "Plugins" icon on the left-side of the window. The icon looks like a blue Lego piece.
Scroll through the plugins and click the "Enable" button next to "VLC Media Player."
