如何在Firefox-Selenium中添加From请求头？

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.firefox.service import Service
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

firefox_options = Options()
firefox_options.add_argument("--headless")  # 无头模式，可选
firefox_profile = webdriver.FirefoxProfile()
firefox_profile.set_preference("general.useragent.override", "Your User Agent")  # 设置User-Agent，替换为你的自定义值
firefox_profile.set_preference("from", "Your From Header")  # 设置From请求头，替换为你的自定义值

# 替换为你的Firefox可执行文件路径
firefox_binary = FirefoxBinary("Path to your Firefox binary")
geckodriver_path = "Path to your geckodriver executable"
service = Service(geckodriver_path)
driver = webdriver.Firefox(service=service, options=firefox_options, firefox_binary=firefox_binary, firefox_profile=firefox_profile)

driver.get("https://www.example.com")  # 访问网页，替换为你要访问的网址
# 执行其他操作...
