FF 16 (Aurora channel), Windows 7 here: no noticeable issues. Memory usage showed about 350 MB, and that's not remarkably far from regular usage numbers anyway.
Memory usage jumped to about 2GB before the machine became totally unresponsive. I did something else for a few minutes while I waited for the kernel to kill anything using too much memory and get my machine back to a usable state.
