My mouse cursor is suddenly extremely slow whenever firefox has focus. Instead of crossing the entire screen with a small hand movement, I get maybe 1/10th of the width of the screen with the same movement.

No one has any ideas or advice? I'm on the verge of shelving Firefox over this - the behaviour is unique to Firefox and is incredibly frustrating, especially when I'm switching between the browser and anything else where my cursor isn't crawling along like a one legged turtle.
