I accidentally downloaded firefox twice, and I can't find where to delete the one I don't need, it's not allowing me to use the start button to change users or anything else. I would like to know how to delete the one firefox browser, I can't get into the area where I can add or delete anything, without being able to use the start button to navigate anywhere. I think I just need to get rid of the second firefox, my troubles started when I downloaded the second one. thanks
