I like this monitor, well not really a monitor as much as a 37" Vizio HD TV LoL. It was only $310 after tax so I had to get it. LoL
The first IE is 32 Bit and the second is 64 Bit. With the FF since they made such a drastic change in 4 and beyond, I kept 3 so that I could be sure that all website would work on it. Sorta the idea of a backup to see if it is the website or FF having the issue. So the first FF is 3 and the second is 10.
