Open Webif - browser plugin

[trapdoor berk]

Hi,

I'm new to all this so not sure I'm posting in the correct section. I've tried to search the forums and google it but can't see to find the answer.

I've got a Vu+ Duo box running openVix, I can connect to the box fine using OpenWebif and the WebTV looks like a cool feature, however when I try and open that tab I get a message (using Firefox), that a plugin is needed to show the content, so my question is what and where can I download this plugin?

Thanks in advance
