# The following is a kludge to get around the fact that the installer

# root permissions; thereby making uninstalling Torbutton from inside
# Firefox impossible.  The user will be caught in an endless loop of
# uninstall -> automatic re-installation of Torbutton.  The OSX
# installer doesn't tell you the owner of Firefox, therefore we have to
# parse it.
