javascript - Selenium Firefox 与 Python3 FirefoxProfile.set_preference() 被忽略

Question

我试图通过 Python 3.4 在 selenium 2.53.1 驱动的 Firefox 45.0.1 上设置不同的首选项值。例如。禁用 JavaScript:

>>> from selenium import webdriver
>>> profile = webdriver.FirefoxProfile()
>>> profile.set_preference('javascript.enabled', False)
>>> driver = webdriver.Firefox(firefox_profile=profile)

但是，这被忽略，about:config 显示

javascript.enabled  true

并且JavaScript代码正常执行。虽然 about:config 确实显示它是用户设置的。缺少什么？
