Firefox disable the add on I'm developing

Question

I'm developing an Firefox add-on with it's latest jpm SDK.

After I done the major code, I use jpm run command to run the extension.

but the addon is disabled. it says "ADDON NAME could not be verified for use in FIREFOX VERSION and has been disabled."

like in the picture. anyone know how to turn off this Firefox feature?

Answer 1

The permanent fix in jpm to avoid having to go to preferences and disable signatures requirement every time you do "jpm run" is to change the preferences.js in your jpm profile, like this:

"xpinstall.signatures.required" : false

in file

npm\node_modules\jpm\data\preferences.js

See this changelist for an example: https://github.com/mozilla-jetpack/jpm/commit/d7f9b51f73d829e65d900a2cb0eed0cbaa957250

Answer 2

From a comment left on a GitHub issue with the same problem last week:

Go to about:config and toggle the xpinstall.signatures.required preference.
