Yes, I do know that.  I was pointing out that I tested Safari, not 
Firefox.

But there are at least three ways to call Firefox on an R URL on a Mac:

via setting options("browser") with name 'firefox' that uses -remote

via setting options("browser") with some other name

via customizing 'open',

and they may well behave differently (but the first two do both work under 
Linux).

I don't have Firefox installed on my Mac (I basically only use it to test 
R things), but on other Unix-alikes 'firefox' is actually a shell script, 
and my guess is that something in that shell script has not been 
customized for the Mac shell in use.  (Another difference is that my MacOS 
is current Leopard and I believe Rolf is on Tiger.)

This is not called 'quoting hell' without reason.
