Firefox Builds for Snippet Development

Tools and Dockerfiles to build Docker Images of Firefox for snippet developement. It's linked to dockerhub as an automated so you can always get up to date images from there.

For example to launch firefox 41:

docker run -t -i -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY firefox-41.0

or Firefox 4:

docker run -t -i -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY firefox-4.0

You can also define a custom Snippets provider with SNIPPET_HOST env variable.

docker run -t -i -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -e SNIPPET_HOST=http://localhost:8000 firefox-4.0


http://localhost refers to containers internal ip, so if you run a development instance on your laptop you probably want to change localhost to the laptop's hostname.

Testing snippets fast

  1. Setup your local snippets server
  2. Setup the snippet template and snippet
  3. Copy ./bin/ to ./bin/ and update SNIPPET_HOST to your host.
  4. Run ./bin/

The final step will sequentially start Firefox browsers from version 15.0 to the latest version. The browser gets auto-configured to fetch snippets from your server thus you only have to check that the snippet is OK and then close the browser window. In a moment the next Firefox version will appear.

You can avoid setting SNIPPET_HOST and test the production snippets against multiple versions of Firefox.


  • SNIPPET_HOST to set snippet server
  • PRODUCT_NAME to set product name to something other than %NAME%. Useful when testing specific snippets with Client Match Rules that set product name.
