WebDriverException: Error: Permission denied to access property “navigator”

Тут такое дело — с «магией» столкнулся: Код работает нормально на Ubuntu 16.04, а на Ubuntu 15.10 падает с ошибками:

org.openqa.selenium.WebDriverException: Error: Permission denied to access property "navigator"
org.openqa.selenium.WebDriverException: Error: Permission denied to access property "document"

Стек трейс:
