we need a more recent version too. This is the one used in the WebExtension

the `chrome` directory no longer has any .js and eslint complain about it.

     "test": "node test_runner.js",
     "posttest": "npm run eslint",
     "resources": "node build/make_resource.js",
     "updatepsl": "node build/updatepsl.js"
   }
 }
