Now, if only they'd fix the AJAX issue, I'd be happy (Firefox pauses while an AJAX update is taking place, even in a different tab).
Did a run in a Windows VM on a different PC (I had upgraded the host from FF 17 to FF 18 already). Host is almost the same as above, save it runs Windows 7 and has a 3.1GHz Core 2 Duo
FF 17 - 263ms
FF 18 - 312ms (18% slower)
