Hi, apart from being able to use more RAM, and generally perform better, the only difference from a security standpoint is that as well as avoiding address space exhaustion problems, a security feature known as ASLR (https://en.wikipedia.org/wiki/Address_space_layout_randomization) works much better in 64-bit applications than in 32-bit applications, so 64-bit Firefox will be slightly more secure.
