You need 8GB of memory to efficiently compile Firefox, but you can run it in a lot less than that. Fundamentally when compiling the application you aren't running the application, you're running the compiler. They are different pieces of software with independent resource requirements. Even if they happen to be similar, that's really just a coincidence.
