本文，直接给出完整的代码，都经过严格验证通过，具体请见注释

Python + Firefox + 插件（closeproxy.xpi）

其中，closeproxy.xpi文件，需要Google、Bing搜下都能搜到下载地址

完整的测试代码如下：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.proxy import *
from pyvirtualdisplay import Display
from base64 import b64encode
 
 
proxy = {
    "host": "123.57.78.100",
    "port": "12345",
    "user": "username",
    "pass": "password"
}
 
profile = webdriver.FirefoxProfile()
 
# add new header
profile.add_extension("modify_headers-0.7.1.1-fx.xpi")
profile.set_preference("extensions.modify_headers.currentVersion", "0.7.1.1-fx")
profile.set_preference("modifyheaders.config.active", True)
profile.set_preference("modifyheaders.headers.count", 1)
profile.set_preference("modifyheaders.headers.action0", "Add")
profile.set_preference("modifyheaders.headers.name0", "Proxy-Switch-Ip")
profile.set_preference("modifyheaders.headers.value0", "yes")
profile.set_preference("modifyheaders.headers.enabled0", True)
 
# add proxy
profile.set_preference('network.proxy.type', 1)
profile.set_preference('network.proxy.http', proxy['host'])
profile.set_preference('network.proxy.http_port', int(proxy['port']))
profile.set_preference('network.proxy.no_proxies_on', 'localhost, 127.0.0.1')
#profile.set_preference("network.proxy.username", 'aaaaa')
#profile.set_preference("network.proxy.password", 'bbbbb')
 
# Proxy auto login
profile.add_extension('closeproxy.xpi')
credentials = '{user}:{pass}'.format(**proxy)
credentials = b64encode(credentials.encode('ascii')).decode('utf-8')
profile.set_preference('extensions.closeproxyauth.authtoken', credentials)
 
profile.update_preferences()
 
driver = webdriver.Firefox(profile)
driver.get("https://proxy.mimvp.com/ip.php")
print driver.page_source
 
driver.quit()
