For some reason, the formatting tools do not work in FF. If you click on one of them, nothing happens. Nothing even pops up in the Firebug console, which is weird.

I had noticed that you were working on them.
Now I get a pop-up with a number. 
Works fine though!
Yep, they are working now. Thanks Josh!
