We use a script, for both firefox and chrome, the chrome one looks like:
#!/bin/sh
# Get current stable build version number of Chrome from the web, do this in a single line to keep it encapsulated

# Get version number on currently installed Chrome app
installed_version="$(/Applications/Google Chrome.app/Contents/MacOS/Google Chrome --version | grep -iE "[0-9.]{10,20}" | tr -d " <>-:;/,&"=#[a-z][A-Z]")"

# Let things settle down
sleep 1
# Detach the dmg and remove the temporary mountpoint
hdiutil detach "${tmp_mount}" && /bin/rm -rf "${tmp_mount}"
if [ -e "/Applications/Google Chrome.app" ]; then
echo "******Latest version of Chrome is installed on target Mac.******"

}

{
