 Running the unit tests
 ----------------------
 
 To verify your changes you can use the unit test suite located in the _qunit_
 directory of the repository. In order to run the unit tests go to the
 extension's Options page, open the JavaScript Console and type in:
 
     location.href = "qunit/index.html";
 
 The unit tests will run automatically once the page loads.
+You can also run these tests with a headless Firefox process. Install the
+dependencies first:
+
+    npm install
+
+Start the testing process:
+
+    npm test
 
 Linting
 -------
 
 You can lint the code using [ESLint](http://eslint.org).
 
 You will need to setup first. This will install our configuration
 [eslint-config-eyeo](https://hg.adblockplus.org/codingtools/file/tip/eslint-config-eyeo)
 and everything needed after you run:
 
     npm install
 
 Then you can run to lint the code:
 
     npm run lint
