将 Selenium 3.8.1 与 Python 2.7 与 Firefox Portable 54、64 位一起使用，运行此脚本时出现以下错误消息:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
binary_argument = FirefoxBinary(r'C:\Users\[removed]\FirefoxPortable.exe')
driver = webdriver.Firefox(firefox_binary=binary_argument)
driver.get("http://icanhazip.com")
.
Traceback (most recent call last):

driver = webdriver.Firefox(firefox_binary=binary_argument)

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities
在它消失之前，我确实看到了启动画面。同样值得注意的是，浏览器在手动使用时工作正常。
我怀疑可移植浏览器需要切换一些设置以允许 Selenium 接管，但这就是我所知道/怀疑的范围。
感谢您对此的任何帮助。
请您参考如下方法:
通过修改 DesiredCapabilities 解决:
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
binary_argument = FirefoxBinary(r'C:\Users\[removed]\FirefoxPortable.exe')
capabilities_argument = DesiredCapabilities().FIREFOX
capabilities_argument["marionette"] = False
driver = webdriver.Firefox(firefox_binary=binary_argument, capabilities=capabilities_argument)
driver.get("http://icanhazip.com")
