&lt;p&gt;Feel free to try out the different features that are provided, please note that the MCImageManager and MCFileManager specific functionality is part of our commercial offering. The demo is to show the integration.&lt;/p&gt;
&lt;p&gt;We really recommend &lt;a href="http://www.getfirefox.com" target="_blank"&gt;Firefox&lt;/a&gt; as the primary browser for the best editing experience, but of course, TinyMCE is &lt;a href="../wiki.php/Browser_compatiblity" target="_blank"&gt;compatible&lt;/a&gt; with all major browsers.&lt;/p&gt;
