Actually, they started the memshrink project two years ago, and the result has been dramatic improvements in memory usage.

That's from a while ago.
They also aggressively handled memory leakage in addons recently.
Their JS performance has dramatically increased recently w/ IonMonkey and the baseline compiler. They also introduced asm.js.

They also switched to multi-process and sandboxing in FirefoxOS, although apparently addon support makes that problematic on the desktop, although they do use multiple threads for various operations on the desktop. (You can of course sandbox firefox itself on most operating systems if you so desire, just like any other process)
