I downloaded Firefox and when i click on icon on the desktop, it partially opens and then a box pops up asking if I want it to be my default browser and when I try to click on no or uncheck the box that reads, don't ask this question in the future, my mouse starts to react like it's trying to open, but it don't, comes back with not responding. I even tried the capability section and to no avail.. I can't get it to work... I have a new laptop, an HP Pavilion g series, windows 7 and an Intel 13 Core processor.. It's a brand new computer and Firefox will not open..I would appreaciate any input on this matter.. Thank you, Marlene
