python selenium firefox-add_扩展无效

import selenium
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.firefox.options import Options as options


def establish_browser(type, hide):
    browser = ''
    if type == 'firefox':
        ops = options()
        ops.add_argument("--headless") if hide is True else ops.add_argument("--head")
        profile = selenium.webdriver.FirefoxProfile()
        profile.add_extension(extension='uBlock0@raymondhill.net.xpi')
        browser = selenium.webdriver.Firefox(firefox_profile=profile, executable_path='geckodriver.exe', options=ops, firefox_binary=FirefoxBinary('C:/Program Files/Mozilla Firefox/firefox.exe'))
    return browser

browser = establish_browser('firefox', False)

如何改变这一点,使uBlock正常工作?

chrome版本似乎正在工作

if type == 'chrome':
    from selenium.webdriver.chrome.options import Options as options
    ops = options()
    ops.add_argument("--headless") if hide is True else ops.add_argument("--head")
    ops.add_extension("ublock.crx")
    browser = selenium.webdriver.Chrome(executable_path='chromedriver.exe', options=ops, desired_capabilities={'binary_location': 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe'})

Firefox贬值了吗?
