I had to stop using Firefox, because the 64-bit version apparently exists only to consume all of the memory on my PCs, not just some of it, like the 32-bit builds would. I'm using Iron Browser now, which has its own issues, but which at least handles a hefty amount of tabs and some essential extensions without destroying system performance.
