Haters-be hate'n.
And how exactly does the one process per tab of chrome address memory issues? Chrome is complete garbage for me after 30ish tabs. Talk about unresponsive...
The great thing about this model is that closing the tabs kills the processes and therefore frees up memory. Last time I used FFx extensively (6 months-1year ago) I could not say the same thing, even after they announced having a pretty major fix for leaks.
