### NOTE: Here you (can) choose whether you are trying to 'fix' google-chrome(-beta/-dev), chromium-browser or iron

## Google-chrome(-beta/-dev) users select this one (default):
_destdir=/opt/google-chrome && _exec=${_destdir}/google-chrome

## Chromium-browser users (uncomment this & comment the Google-chrome one (in case you use chromium-browser)):
#_destdir=/opt/chromium-browser && _exec=/usr/bin/chromium-browser

## Iron users (same thing):
# _destdir=/opt/iron && _exec=/usr/bin/iron

# For the wget (download) section (to get the correct file)
