Somewhat recently I have been unable to use my scroll wheel to scroll pages up and down. I can scroll up and down in every application on my computer except Firefox. Things I've already tried: I've tried turning hardware accel. on and off I've tried turning off auto scroll and scroll lock. I've tried using other mice. I've tried using a different Firefox profile. I've tried restarting my computer. I have been AVOIDING doing any changes that erase my cache or restart Firefox in anyway since I REALLY don't want to lose any of my password and history data. If it's the only way, then I'll deal with it when I deal with it. What makes this problem weirder is that I can middle-mouse click and scroll the page up and down with that, but I cannot scroll the page manually with the wheel at all. What could possibly be the issue? Someone please help! It's not like it's making me terribly angry, but it's very, very inconvenient and no normal fixes seem to be fixing this super simple issue.
