Posting recommended system requirements doesn't give those of us with older systems enough information to decide whether downloading the latest version is a reasonable risk. For example, you currently recommend Pentium IV etc. That doesn't tell me if my Intel duo core 1.66 GHz will work (albeit more slowly), if I should stick with an older version of Firefox, or if Firefox just no longer meets my needs. Posting minimum system requirements would be a HUGE help. After all, who among us, doesn't want the most secure environment possible?
