#ff_home是firefox-bin所在目录
ff_home="/opt/firefox"
MOZILLA_FIVE_HOME=$ff_home
LD_LIBRARY_PATH="${ff_home}:${ff_home}/plugins"
DYLD_LIBRARY_PATH=$ff_home
LIBRARY_PATH="${ff_home}:${ff_home}/components"
SHLIB_PATH=$ff_home
LIBPATH=$ff_home
ADDON_PATH=$ff_home
eXPort MOZILLA_FIVE_HOME LD_LIBRARY_PATH DYLD_LIBRARY_PATH LIBRARY_PATH SHLIB_PATH LIBPATH ADDON_PATH
