我正在使用Python和Selenium远程控制Firefox浏览器。根据mozilla开发者网站的指示，我已经切换到使用Marionette，并且一切正常。
但是，在一个页面上当我想选择一个元素时，会出现异常。我认为这可能是Javascript警告导致驱动程序崩溃。有没有人知道如何让驱动程序对Javascript错误更宽容？此外，有没有人知道Python Marionette客户端的全面文档在哪里可以找到？
抱歉，由于我正在尝试从客户的私有网站中选择一个元素，因此无法使代码完全可重现。

from selenium import webdriver
# see https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
caps["binary"] = "/Applications/Firefox.app/Contents/MacOS/firefox-bin"
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
browser = webdriver.Firefox(capabilities=caps)
webdriver.Firefox.get_capabilities()
browser.implicitly_wait(3)
browser.get("https://www.example.com/examplepage")
saved_exports_field = browser.find_element_by_id('exportlist')
saved_exports_field_select = Select(saved_exports_field)
这就是出错的地方。跟踪信息如下：
