Sometimes, profile.set_preference("javascript.enabled", False) does not work in Firefox. Use the below python to get around this:

 from pyvirtualdisplay import Display
 from selenium import webdriver
 from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
 from selenium.webdriver.common.keys import Keys
 from selenium.webdriver.common.action_chains import ActionChains


 profile = webdriver.FirefoxProfile()
 profile.update_preferences() #May or may not be needed

 display = Display(visible=0, size=(1200, 800))
 display.start()

 browser = webdriver.Firefox(profile)
 browser.get("about:config")
 actions = ActionChains(browser)
 actions.send_keys(Keys.RETURN)
 actions.send_keys("javascript.enabled")
 actions.perform()
 actions.send_keys(Keys.TAB)
 actions.send_keys(Keys.RETURN)
 actions.send_keys(Keys.F5)
 actions.perform()

 browser.quit()
 display.stop()
