So, I tested this in Ubuntu 14.04 LTS and Firefox 38. This tool did not worked in Chrome 43.
You will need to add the PPA to your Ubuntu box and then install the program.
- open “Terminal”
- type “sudo add-apt-repository ppa:mjblenner/ppa-hal”. Then go through the prompts
- then, type “sudo apt-get update && sudo apt-get install hal”
- Open up Firefox and give it a ride!
