I get where everyone is coming from when they say Firefox is getting better, but I really don't see Chrome getting worse and I certainly don't see Firefox surpassing Chrome.

Firefox dev tools in Nightly are much better, but still don't beat Chrome's. Firefox is still ugly. Firefox still won't let me open Nightly and Aurora. Firefox's Javascript performance is getting faster and memory usage is getting better, but when running tight loops in Javascript doing lots of calculations (specifically rendering fractal flames) Firefox becomes unresponsive and unusable, where as Chrome is fine and I can still browse normally while it runs in the background. Chrome might use a but more RAM but that's not a problem for me. I have buckets of RAM. Firefox needs restarting all the time when I change extensions or get updates.

I'll stick with Chrome for now. :)
