Add-ons, unlike plugins, are automatically checked for updates once every day. In Firefox, updates are automatically installed by default. Versions of Firefox prior to 4 (and other applications) will alert you that updates to your add-ons are available. <a href="%(plugin_url)s">Plugins</a> are not currently automatically checked for updates, so be sure to regularly visit the <a href="%(plugincheck_url)s">Plugin Check</a> page to stay up-to-date.
附加组件，与插件不同，会每天自动检查一次更新。在 Firefox 中，默认自动安装更新。版本大于4的 Firefox （以及其他应用程序）在有可用的附加组件更新时会提醒您。<a href="%(plugin_url)s">插件</a>目前不会自动检查更新，因此要确保定期访问<a href="%(plugincheck_url)s">插件检查</a>页面以保证版本更新。
