You know, I've used that button before, but for some reason I cannot seem to find it in this browser today.
EDIT: Wait, never mind, found it. There was something weird going on with one of my security programs and firefox earlier, though. I figured out part of problem. For some reason it was having trouble remembering I was logged in, so when I viewed my own comments I couldn't edit them. The fact it still treated me as logged in when I went to post new ones is the odd part.
