options(browser="/usr/bin/firefox")

is one way. Setting the environment variable R_BROWSER (before
starting R) is another. And meddling with the Renviron file, personal
or system-wide, is a third method.

This information does seem to be a bit tricky to dig out from the R
documentation, especially the R_BROWSER bit. I can only find a
somewhat oblique reference in the R-admin manual and of course
?Startup points you towards the Renvironment files and
$RHOME/etc/Renviron demonstrates what you can set and how.
