Not working !?!

Config of my ckeditor:

`CKEDITOR.editorConfig = function( config ) { config.uiColor = '#ffffff'; config.language = 'pt-br';

config.filebrowserBrowseUrl = CKEDITOR.basePath + 'kcfinder/browse.php';
config.filebrowserImageBrowseUrl = CKEDITOR.basePath + 'kcfinder/browse.php?type=images';
config.filebrowserImageUploadUrl = CKEDITOR.basePath + 'kcfinder/upload.php?type=images';
config.enterMode = CKEDITOR.ENTER_BR;
config.extraPlugins = 'richcombo,youtube,strinsert';
//config.extraPlugins = 'strinsert';
	
config.toolbarGroups = [
	{ name: 'clipboard' },
	{ name: 'editing', groups: [ 'find', 'selection'] },
	{ name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ] },
	{ name: 'colors' },
	{ name: 'links' },
	{ name: 'insert' },	
	{ name: 'paragraph',   groups: [ 'list', 'align' ] },
	{ name: 'tools' },
	{ name: 'styles' },
];
 
config.removeButtons = 'Source,Save,Print,NewPage,Preview,Styles,Font,Anchor,PageBreak,Maximize,Superscript,Subscript,Flash,Iframe,ShowBlocks';
config.format_tags = 'p;h1;h2;h3;pre';
config.removeDialogTabs = 'image:advanced;link:advanced';
config.autoUpdateElement = true;
config.removePlugins = 'elementspath';
config.resize_enabled = false;	

};

But the plugin not is visible, any idea ?
