我该如何使Selenium使用我的firefox（而不是创建新的）

Question

I am new to selenium.
I found selenium would not use my local firefox browser. Seems it create a fresh one with no plugin.
But I want do something with plugin on, such as: modify request headers , aotuproxy . I only found setting headers example in java.
Though proxy can be set by using webdriver.FirefoxProfile().set_preference('network.proxy.http',.... , it is not so sweet to fit my aim.
So I think it would be very nice to make selenium use my firefox. But I can not figure it out.

Answer 1

Selenium cannot connect to an existing browser. It can only launch new instances.

Answer 2

Ok, I find the answer.Give a profile path is the point.

def get_ffprofile():
    ff_profile_path = 'C:\\Users\\Kasim\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\my89fce2.default'
    ff_profile = webdriver.FirefoxProfile(ff_profile_path)
    return ff_profile

then

browser = webdriver.Firefox(firefox_profile=get_ffprofile())

Will start my browser(actually a browser instance with my custom profile in another word)
