Jenkins - Невозможно загрузить браузер "firefox"

Question

Я настраиваю модульное тестирование пользовательского интерфейса karma на сервере jenkins, и я хочу запустить браузер firefox от Jenkins. При выполнении процесса сборки я получаю следующие ошибки из консоли Jenkins.

Не уверен, как установить плагин firefox в jenkins.
