why does caps lock close firefox.

When I am in firefox. If I press the CAPS LOCK key I get a pop up box asking me if I want to CLOSE firefox.

I do NOT want to close firefox whenever I press the CAPS LOCK key.

Why is this happening and how can I fix this?

Do you have that problem when running in the Firefox SafeMode?

Don't select anything right now, just use "Continue in SafeMode."

If not, see this:
