AIUI, on Windows the smallest block you can ask for with VirtualAlloc is 4 KiB. However, no more than one VirtualAlloc block can exist per 64 KiB chunk. So if you ask for 4 KiB you'll end up wasting the remaining 60 KiB of address space in the 64 KiB chunk. Assuming I'm right about this (I'm fairly certain, but not 100%), it sounds like some code (be it Mozilla or driver code) is VirtualAlloc'ing lots of 4 KiB blocks, and thus wasting lots of address space.
