This is really strange and I'm not even sure it's a WP problem but I can't replicate the problem anywhere else except in WordPress.
When I'm typing a post if I hit the apostrophe (') or the forward slash (/), instead of typing those items, it brings up the Quick Find toolbard at the bottom of Firefox. It's never done this before. It just started a couple days ago.
I figured it had something to do with preferences or some sort of key command I hit on accident, but I can't fix it. Does anyone have any idea what I did and how I might be able to change it back? I'm at a loss.
