Karma can not load browser launcher

 [launcher]: Cannot load browser "FireFox": it is not registered! Perhaps you are missing some plugin?

I've followed all the steps ( that I know of ) : 

npm install karma-firefox-launcher --save-dev

karma.conf.js

plugins: [
  require('karma-jasmine'),
  require('karma-firefox-launcher'),
  require('karma-ie-launcher'),
  require('karma-jasmine-html-reporter'),
  require('karma-coverage-istanbul-reporter'),
  require('@angular-devkit/build-angular/plugins/karma')
],

\node_modules\karma-firefox-launcher\ is present as expected

package.json

  "devDependencies": {

    "karma-firefox-launcher": "^1.1.0",

NOTE : I have no problem with launching IE browser

Could this be a misleading error where the real problem is that Karma can't find Firefox.exe ?

You also need to add into the browsers property the name of the browser you want to launch, in this case "Firefox":

browsers: [/*'Chrome'*/, 'FirefoxDeveloper', 'Firefox'],
