Ok weird problem I've been experiencing in the last few days. A few times when I tried to reply to a message and click reply it will ask me if I want to leave the page or stay. It will post the message, but send me to a page with my post open like I'm still typing and say I tried posting a duplicate post. It usually does that when you type something, but decide not to post and hit back or something, but never when replying. It still posts, but that comes up. I don't know if it's a problem with the new Firefox or what.
