I don't know much about Jetpack or Elrolysis, next to nothing in fact. Best place to begin would be with the "Getting Started" tutorial https://developer.mozilla.org/en-US/Add-ons/SDK/Tutorials/Ge... Installation instructions here https://developer.mozilla.org/en-US/Add-ons/SDK/Tools/jpm#In.... Caveat I haven't used the updated SDK using their jpm tool but my FF 41 is happily running addon packaged with out-of-date SDK. Good news for you is the new work-flow sounds even easier as you no longer need to call bin/activate to use cfx tools. I will eventually update SDK but I was perfectly happy with my old solution: alias ffsdk='cd /home/$USER/addon-sdk-1.17 && source bin/activate && PS1="ffsdk:\W$ "'
