How to run Firefox extension using Firefox Developer Edition and jpm?

Question

I'm having some inconvenient with current release Firefox version and want to switch to Dev edition to developing my extension.

I've tried the tutorial in this link but doesn't work. The example is for nightly build, which I guess is the folder name, but replace it doesn't work. And also created a system environment doesn't help too.

Thank you in advance.

Answer 1

-b expects the path to the executable, not the folder. On Windows, I used jpm run -b "C:\Program Files (x86)\Firefox Developer Edition\firefox.exe" and it worked fine.

Answer 2

Alternatively you can set the JPM_FIREFOX_BINARY environment variable with the path to the version of Firefox you want to run, e.g. C:\Program Files (x86)\Firefox Developer Edition\firefox.exe. So when you invoke jpm run or jpm test without the -b option, jpm first checks JPM_FIREFOX_BINARY, and use this as the path if it is set.
