This is a Heroku buildpack for Firefox. Meant to be used in combination with something like xvfb, for headless operation.
Example usage:
$ heroku create --stack cedar --buildpack https://github.com/bensomers/firefox-buildpack
# or if your app is already created:
$ heroku config:add BUILDPACK_URL=https://github.com/bensomers/firefox-buildpack
$ git push heroku master
If you're using heroku-buildpack-multi to include other buildpacks, you should set environment variable by your own to include following paths.
PATH="/usr/local/bin:/usr/bin:/bin:/app/vendor/firefox"
LD_LIBRARY_PATH="/usr/local/lib:/usr/lib:/lib:/app/vendor/firefox"
