Editor buttons, smileys etc not working in Firefox
 

Hi, I have a problem that has only just started.

In the editor when replying to a message or creating a new thread, none of the editor buttons or smileys work. When you click on them nothing happens and when hovering over them they don't highlight or anything.

I tried it in IE and it works fine on that, so I really don't know what's wrong with it. I tried using the default vBulletin style and the same thing happens on that too. :confused:

Here's the link to my forum in case it's needed; http://www.simpsonsboard.com

Anyone got any ideas? Thanks! :)
