Before You InstallEdit

Close Firefox before installing pluginsEdit

Firefox should be closed before running any plugin installation programs, as existing files may be overwritten during the installation process.

Close Quick Launch before installing pluginsEdit

If you have Quick Launch enabled on Windows, you will also need to close it prior to installing plugins. If you are installing several plugins, you may wish to disable it until you are finished. To do this, right-click in the Quick Launch icon in your taskbar, and select the appropriate option (Close or Disable).

Checking which plugins you have installedEdit

To check what plugins you have installed from the Options menu (Tools -> Options -> Downloads -> Plugins).

Using XPInstall to install pluginsEdit

Some plugins are available as XPInstall packages (XPIs). Where XPIs are available, it is recommended you use them as they often install the plugin completely automatically. After the XPI has finished installing, you should restart your browser.

XPInstall for plugins works for Firefox releases up to and including Firefox 0.8.

Uninstalling PluginsEdit

Mozilla Firefox looks for plugins under the Mozilla profiles directory instead of it's own profiles directory. If you want to remove a plugin for Mozilla Firefox, but not Mozilla, you will have to relocate it to the plugins directory of your Mozilla installation (Bug 172891).
