This morning, upon opening Firefox, I noticed that I could not scroll through any pages or windows. I turned off scroll lock (or so I thought), and it began scrolling. But then, in all of my other windows, scroll lock was activated. So, I hit my scroll lock button again, and now all other windows will scroll except for Firefox. Is there a setting I need to change?

It appears as if scroll lock is reversed on Firefox vs. all other apps on my computer.
