How to manage firefox extension in selenium?

Question

Python

Installed via selenium extension to use proxy, but I don't know how to connect now. Nobody knows how to manage extensions through selenium ?

Installed like this

firefox_binary = '/usr/bin/firefox-developer-edition'
driver = webdriver.Firefox(firefox_binary=firefox_binary)
driver.install_addon("/home/foxyproxy.xpi", temporary=True)

driver.close()
driver.quit()

Answer 1

Through selenium - no way.
Proxy with password can be used by installing selenium-wire
pip install selenium-wire
Use like this:

from seleniumwire import webdriver
options = {
'proxy': {
    'http': 'http://username:[email protected]:port',
    'https': 'https://username:[email protected]:port',
    'no_proxy': 'localhost,127.0.0.1,dev_server:8080'
    }
}
driver = webdriver.Firefox(seleniumwire_options=options)

Plan B:
Tweak this extension's sqlite database in the user's profile. Proxy settings are stored there in binary form, but the format is simple, at first glance
