Python Selenium Firefox - how to enable headless-mode as part of a class/object?

I have the following code:
options = Options()
options = options.set_headless( headless=True)
class Sel_Driver():
def __init__(self):
self.driver = webdriver.Firefox(firefox_options=options)
I can then use self.driver.get(url) as part of a method to open urls I feed in. This works - I can feed in and open the URLs, but they don't in headless mode.
(I initially defined the driver as self.driver = webdriver.Firefox(firefox_options=Options().set_headless(headless=True) - but that didn't work, so I tried it as above).
What am I missing? I don't understand why the driver is able to open pages, but the options aren't enabled.

Please try following code :
options = Options()
options.add_argument("--headless")
driver = webdriver.Firefox(firefox_options=options)

This will work for you for sure. Try it.Please specify the path of the driver. It is for chrome change it to firefox.
from pyvirtualdisplay import Display
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless")
driver = webdriver.Chrome(chrome_options=options, executable_path="C:\\Users\\Username\\Downloads\\chromedriver.exe")
print("Firefox Headless Browser Invoked")
driver.get('https://www.facebook.com/')
jks = driver.find_element_by_id("email").get_attribute("class")
print(jks)
driver.quit()

How to disable chrome notifications popup in python and selenium?

How to disable chrome notifications popup in python and selenium?
I tried:
chrome_options = webdriver.ChromeOptions()
prefs = {"profile.default_content_setting_values.notifications" : 2}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)
But then also it shows notification...
I tried the same codes answered
here but then also I
am not able to disable the notifications!

The selenium package has a ChromeOptions class, in which you can add many arguments. One of which is 'disable-notifications'. You can pass that class to the driver class when initializing it.
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('disable-notifications')
driver = webdriver.Chrome('chromedriver.exe', options=chrome_options)

from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('disable-notifications')
driver = webdriver.Chrome(executable_path="C:\Users\PycharmProjects\chromedriver_win32\chromedriver.exe", options=chrome_options)
driver.maximize_window()
This works with the right placement of code:

You can pass disable-notifications to your chrome options.
Here's an example I have using Javascript, should work the same with Python.
var o = new chrome.Options();
o.addArguments('user-data-dir=./chromeprofile');
o.addArguments('disable-infobars');
o.addArguments("disable-notifications");
o.setUserPreferences( { credentials_enable_service: false } );

Headless not working for windows

I am trying to run headless Chrome and it running normally without headless it just runs Chrome as normal. I have updated chrome recently so that's not the issue.
driver.maximize_window()
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('headless')
browser = webdriver.Chrome(chrome_options=options)
driver.get('https://www.youtube.com.au')

You need to make a couple of changes to your code block as follows :
You need to maximize the browser once the webdriver opens the browser instance.
As per best practices to maximize the Chrome Window use Options() Class.
To maximize the Chrome Window through Options() Class either use the start-maximized argument or use the window-size argument.
Here is the sample code block for your reference:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
options.add_argument("--headless");
options.add_argument("window-size=1400,600");
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("http://google.com/")
print ("Headless Chrome Initialized")

Disable python chrome driver extensions without lose driver path

I started having issues running a python script which uses selenium and chrome driver, so I want to disable extensions of chrome driver using python without losing the path where the driver is located.
Currently I have the below:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
path_to_Ie = 'C:\\Python34\\ChromeDriver\\ChromeDriver.exe'
browser = webdriver.Chrome(executable_path = path_to_Ie)
url = 'https://wwww.test.com/'
browser.get(url)
and I would like to add the below lines:
chrome_options = Options()
chrome_options.add_argument("--disable-extensions")
browser = webdriver.Chrome(chrome_options=chrome_options)
Any idea how I can merge both codes to make it work properly?
Thanks a lot.

Just provide multiple keyword arguments:
chrome_options = Options()
chrome_options.add_argument("--disable-extensions")
browser = webdriver.Chrome(executable_path=path_to_Ie, chrome_options=chrome_options)

How to start Chrome with webdriver and quic disabled?

I need to start chrome with webdriver with quic disabled as follow:
--flag-switches-begin --disable-quic --flag-switches-end
I am using python with selenium 2.47.3
from selenium import webdriver
from selenium.webdriver.chrome.options import Options as ChromeOptions
options = webdriver.ChromeOptions()
options.add_argument("--disable-quic")
_browser = webdriver.Chrome(chrome_options=options)
Doing that does not put --disable-quic in between --flags-switches-begin and end.

In case anyone is still looking for this, the correct way to do this is:
options = webdriver.ChromeOptions()
options.add_argument("disable-quic") # not "--disable-quic"
_browser = webdriver.Chrome(options=options)
