[尝试将FoxyProxy扩展名添加到Firefox驱动程序时：
from selenium.webdriver import FirefoxProfile, DesiredCapabilities
from selenium import webdriver
profile =FirefoxProfile()
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = False
profile.add_extension(extension='res/[email protected]')
profile.set_preference("extensions.logging.enabled", True)
driver = webdriver.Firefox(profile,capabilities=firefox_capabilities)
一切似乎都很好，但是当窗口打开时，我看到未安装FoxyProxy，浏览器控制台也显示以下消息：
1566128038983 addons.xpi-utils DEBUG New add-on [email protected] installed in app-profile

这意味着扩展名未正确签名。购买了xpi文件，直接从我的常规个人资料扩展名文件夹中复制了该文件，所以我不明白为什么出现此警告？实际上这是安装失败的根源。
