Unfortunately, looks like the CPU spikes are still a problem on OS X for me.
I check this every time a new version is released as I'd love to make the switch from Chrome, but Firefox with one blank tab and no extensions uses more CPU than Chrome with 15 actual tabs. When I actually throw activity at Firefox it hogs the CPU even more.

Here's hoping v61 addresses it.
