If you were migrated to 64-bit but want 32-bit, you can install 32-bit 56.0.1 or later and not be re-migrated. 32-bit Firefox = 56.0.1 will be updated to the latest 32-bit release (currently 56.0.2), but will not be migrated.Which Firefox versions will be migrated to 64-bit? 2 GB RAM is Microsoft's minimum memory requirement for Windows 7 and 10. For users with less than 4 GB of physical memory, there is a trade-off between the larger virtual address space and the overhead of 64-bit code. Users are eligible for a 64-bit default if they are running 64-bit Windows 7+ and have strictly more than 2 GB RAM (so 3 GB is effectively the minimum memory requirement). 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).
