test is passing if i run the exact same ./run_firefox.sh on my local machine, but if I run it in DO droplet I am getting the log as above... for some reason it is failing at 'openBrowser' step. what can be wrong? docker image tested on droplet? it should be working on droplet since it works on a local machine....

Could you please try again with the new version? We've switched to xvfb-run to start the container's GUI.
