Selenium firefox配置文件无法加载扩展-python

Question

我正在尝试在python硒代码中加载firefox插件。 但是我遇到以下错误。如何解决此问题

Selenium version : 3.13.0
python : 3.6
firefox version : 61.0.1

代码

firefoxProfile = webdriver.FirefoxProfile() 
firefoxProfile.add_extension(extension = "firefoxbinary/ublock1.16.14.xpi")
driver = webdriver.Firefox(firefox_profile=firefoxProfile,executable_path="geckodriver") 
driver.get('http://amazon.com/') 
print(driver.page_source)

错误：

raise AddonFormatError(str(e), sys.exc_info()[2])
selenium.webdriver.firefox.firefox_profile.AddonFormatError: ("[Errno 2] No such file or directory: '/var/folders/f7/cw_7hbmn67q_db74544p0x3srxlj8y/T/tmp08r3_4os.ublock1.16.14.xpi/install.rdf'", <traceback object at 0x10332b248>)

我正在关注http://selenium-python.readthedocs.io/faq.html
