firefox won't allow me to post here using advanced

[shortbus1662]

when trying to post on ANY vb3 forum, using firefox and the advanced editor, I get a text box that won't allow me to type in or even click in. It shows up as the same grey color as the color around this reply box. In standard and basic, it works fine. It goes for this forum, and the other vb forums I post on...

I'm assuming it's something in my settings, or it would have been mentioned a zillion times by others. Any ideas?

Also, when I copy text from another site, and try and post it here, I get a message saying my mozilla settings won't allow this...
