To get information about all installed and available plugins you can use the  PluginManager.getPluginsInfo()  method: (要获取有关所有已安装和可用插件的信息,可以使用PluginManager.getPluginsInfo()方法)
PluginManager pluginManager = browser.getPluginManager();
List<PluginInfo> pluginsList = pluginManager.getPluginsInfo();
for (PluginInfo plugin : pluginsList) {
    System.out.println("Plugin Name: " + plugin.getName());

To enable/disable specified plugin register your own PluginFilter implementation:(要启用/禁用指定的插件,请注册您自己的PluginFilter实现:)

pluginManager.setPluginFilter(new PluginFilter() {
    public boolean isPluginAllowed(PluginInfo pluginInfo) {
        // Allow only PDF plugin
        return pluginInfo.getMimeTypes().contains("application/pdf");
