 Make 64-bit Firefox the default version for new and existing eligible users to reduce our OOM crash rate, increase performance, and improve security (ASLR).
-Users are eligible for a 64-bit default if they are running 64-bit Windows 7+ and have at least 1900 MiB RAM. 32-bit Firefox running on 64-bit Windows OS can use about 3,800 MiB of virtual address space (4 GiB minus overhead from physical memory reserved for the OS and BIOS). For users with less than 4 GiB of physical memory, there is a trade-off between the larger virtual address space and the overhead of 64-bit code.

For users with less than 4 GiB of physical memory, there is a trade-off between the larger virtual address space and the overhead of 64-bit code. We have decided to remove any minimum memory requirement for 64-bit Firefox because we don't want to withhold the security benefits of ASLR. Also, 2 GiB RAM is Microsoft's minimum memory requirement for [https://support.microsoft.com/en-us/help/10737/windows-7-system-requirements Windows 7] through [https://www.microsoft.com/en-US/windows/windows-10-specifications#sysreqs 10].
