I just downloaded and started using this. It seems pretty cool except for it apparently does not work with Firefox. Is this true or am I doing something wrong? Also, does this track my mouse movements as well as mouse clicks?
It works fine with Firefox and Chrome for me. Maybe try switching browsers to see if the problem occurs in both or just one?
I think it does track your mouse movements because you can get a mouse heatmap (Input → 4th section) which shows where your mouse is most active. (Like the keyboard heatmap, but with a mouse. XP)
