Hi, I started playing with web-ext and an addon I wish to modify from this repo:
I cloned it, I installed the npm packages and when I run web-ext run from the base directory the extension loads and it works.
EXCEPT when I click on the extension toolbar icon I get this message
This is the manifest.json

I’m running FF 59.03 64bits on W10
