Of course it does. But not necessarily only in the direction you're hinting! At the end of the day it's not the number of hours worked, but the value created, that determines how wealthy a country gets. Having sufficient vacation and generally taking into account that employees are human beings might have an effect on how happy and productive they are.
I don't know if there are studies lending support to this, but to my mind it seems a pretty plausible thesis. I regard spending some of my tax money on my neighbour staying home with his kids as an investment. Social security is fundamental to human health, crime, education, and ultimately productivity.
To me, that is not all though. GDP growth isn't a goal or an end in itself - it is merely a (very important) means to worthy ends. It would be completely meaningless to have GPD growth if it did nothing to promote "the pursuit of happiness".
For the most part Chrome or Fox or even IE10 behave similarly enough that I can almost use them instead of Opera. I think there's just 2 exceptions. Whenever I use another browser I find myself getting frustrated with 2 things: (1) Nothing happens when I "roll-left" over the mouse buttons (navigate back). (2) Tabs MORONICALLY cycle left-to-right, rather than in most recently used order. Both are show-stoppers for me, and I don't care if a plug-in can fix it, as long as Opera is otherwise more or less on par with the alternatives.
Except the minor detail that any for-profit is in fact legally OBLIGED to maximize profit for its shareholders.
