This is not a serious problem, but while trying to understand some difficulties that R had finding our copy of mozilla, I noticed that the browseURL() function defined in help.start.R includes the lines:

    system(paste(browser, remoteCmd, "2>&1 >/dev/null ||",

                 browser, quotedUrl, "&"))

I assume the intent is to hide the "No running window found" or equivalent message that the remoteCmd might print before trying to start a new instance of the browser. On the shells I've tried, though, you need to reverse the order of the redirections to achieve this, i.e.: ">dev/null 2>&1" instead of "2>&1
>/dev/null".

Apologies if I've misunderstood your intent, or if there are other shells where you need the order you've used.
