Plugins are Firefox add-ons that manage Internet content that Firefox is not designed to process. This article describes how to use and manage plugins in Firefox.

What are plugins?

A plugin is a piece of software that manages Internet content that Firefox is not designed to process. These usually include patented formats for video, audio, online games, presentations, and more. Plugins are created and distributed by other companies.

Note: The 64-bit version of Firefox recognizes and supports only the Adobe Flash and Microsoft Silverlight NPAPI plugins.

Update plugins

Visit the plugin page for the plugin you want to update. Plugins involve using code written by third-parties, so it is critically important to keep your plugins up-to-date. A security vulnerability in a plugin you have installed could compromise your privacy.

Managing plugins

To see what plugins you have installed:

  1. Click the menu button New Fx Menu and choose Add-ons. The Add-ons Manager tab will open.

  2. In the Add-ons Manager tab, select the Plugins panel.

To disable a plugin, select a plugin in the list, then select Never Activate. Disabling a plugin will turn it off without uninstalling it. To re-enable it, select Always Activate.

Uninstalling plugins

  • Visit the article above that corresponds to the plugin you want to uninstall for instructions.
  • For instructions on how to manually uninstall a plugin, see Manually uninstalling a plugin

Troubleshooting

If you have problems with Firefox, they may be caused by a plugin or combination of plugins. For help on how to diagnose plugin problems, see Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems.
