How do I disable the drop-down slider thing that shows "My Profile", "My Content", "Friends", "Ignored" and "Help"?

I've looked at the settings pages, but couldn't find anything. It's really annoying. I've tried signing out and signing back in, but that didn't help.

What browser are you using?
On Firefox, the drop down only shows if I click on my user name.

I, oh just this second figured it out. I am using the NoScript Firefox add-on. I didn't add the forums to the whitelist. Once I did, the drop down menu went away.
