There is have my codes. I want to change it to headless browser. But i am getting an error.
I added screenshot to show error.
This error message...
ERROR:devtools_http_handler.cc(288)] Error writing DevTools active port to file
...implies that there was an error while writing DevTools active port to the required file.
As per the discussion in How to open a Chrome Profile through Python instead of specifying only the directory name through user-data-dir, you need to pass the absolute path of the user-data-dir.
Solution
So you need to replace the line of code:
options.add_argument("user-data-dir=bot_data")
With:
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\bot_data")

What I need
I need to run Selenium with Chrome Profile
Here is my code:
from selenium import webdriver
import time
options = webdriver.ChromeOptions()
options.add_argument("--user-data-dir=/home/atom/.config/google-chrome") #Path to your chrome profile
options.add_argument('--profile-directory=Profile 1')
driver = webdriver.Chrome(options=options)
driver.get('https://youtube.com')
time.sleep(5)
Problem
The code opens Google Chrome instead of Chromedriver. Profile is loaded. But driver.get doesn't work
Question
How can I use Selenium with Chrome profile?
What chromedriver does is briefly described here. When you call get on the webdriver, you are asking for the site to be opened on the chrome browser. If you want to use brave browser or another browser implementation using the chromium engine, you may specify the location of the browser's binary using:
ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/other/chrome/binary");
You may load a specific profile by using:
ChromeOptions options = new ChromeOptions();
options.addArguments("user-data-dir=/path/to/your/custom/profile");
Specifying no profile (not including this option should load the default profile).
A complete list of supported options may be found here.
I am stucking with a script to do the following
I want to open my local chrome in which I have several accounts logged in, so for this I do:
from selenium import webdriver
driver = webdriver.Chrome(executable_path="C:/Program Files (x86)/Google/Chrome/Application/chrome.exe")
but when I do that
driver.get(url)
doesn't send me to the URL I want.
On the other hand if I do it with
driver = webdriver.Chrome()
driver.get(URL)
Everything goes smoothly but it opens it with the chromedriver.exe and therefore the accounts are not logged in.
Any idea how to open the local chrome and then be able to browse?
Any solutions for the problem
You need to load your user profile while initializing selenium webdriver.
You can do it using
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Path to local user profile") #Path to your chrome profile
w = webdriver.Chrome(executable_path="C:\\Path to your local chrome.exe installation", chrome_options=options)
Typing chrome://version/ in chrome address bar will show you the path to user profile.
In automation, when we use Selenium to interact with a web browser, we need a browser driver to communicate with the specific browser. ChromeDriver is the specific driver for Google Chrome. When you use webdriver.Chrome(), it launches the Chrome browser using the ChromeDriver executable. Chromedriver is a bridge between your Selenium script and the Chrome browser exactly as taxi driver is a bridge between you and taxi car.
Chrome uses profiles. By default in tests are not used local profiles of users. The new temporary profile is created instead. However, it is possible to point out the profile which should be used.
You need to pass additional argument user-data-dir to the Chrome options when initialising the Chrome driver, in order to open the local default Chrome profile. If you need to point out specific profile then you should use profile-directory.
Example:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument(r"--user-data-dir=C:/Users/[username]/AppData/Local/Google/Chrome/User Data")
options.add_argument(r'--profile-directory=YourProfileDir')
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get(URL)
To find the profile folder on Windows right-click the desktop shortcut of the Chrome profile you want to use and go to properties -> shortcut and you will find it in the "target" text box.

#TLDR I want to use brave browser with selenium written in python but can't find any current solutions that work.
This code works
from selenium import webdriver
option = webdriver.ChromeOptions()
option.binary_location = r'C:\Program Files\BraveSoftware\Brave-
Browser\Application\brave.exe'
driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe',
options=option)
driver.get("https://www.google.com")
driver.quit()
but executable_path is deprecated:
C:\Users\USER\PycharmProjects\pythonProject\sol2.py:5:
DeprecationWarning: executable_path has been deprecated, please pass in a Service object
driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe', options=option)
Found this on youtube: https://www.youtube.com/watch?v=VMzmVFA-Gps
# import statements
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
# Declare variables and setup services
driverService = Service('C:/webdrivers/chromedriver.exe')
# 1. Passes the chromedriver path to the service object
# 2. stores the service object in the s variable
driver = webdriver.Chrome(service=driverService)
# 1. Passes service object driverSerice into the webdriver.Chrome
# 2. Stores object in driver variable
# Body (actually doing stuff)
driver.maximize_window() # maximizes the browser window
driver.get("https://www.google.com") # navigates to google.com
myPageTitle = driver.title
# gets the title of the web page stores in myPageTitle
print(myPageTitle) # prints myPageTitle to Console
assert "Google" in myPageTitle
# checks myPageTitle to ensure it contains Google
# clean up
driver.quit() # closes the browser
When I run this code I get:
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
This code works as long as you allow Google Chrome onto your PC. I don't want Chrome on my PC.
The problem is that I can't figure out how to get selenium to use brave instead of Chrome.
As of this writing I am using the following:
Windows 11 Home
Selenium v4.0.0
Python v3.10
ChromeDriver 95.0.4638.69
Brave Browser Version 1.31.91 Chromium: 95.0.4638.69 (Official Build) (64-bit)
Can some one please explain how to make this work with the current (read nondeprecated) code on brave browser? Thanks for your time.
To initiate a brave browsing context you need to:
Use the binary_location attribute to point to the brave binary location.
Use the chromedriver executable to initiate the brave browser.
Code block:
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
option = webdriver.ChromeOptions()
option.binary_location = r'C:\Program Files (x86)\BraveSoftware\Brave-Browser\Application\brave.exe'
driverService = Service('C:/Users/.../chromedriver.exe')
driver = webdriver.Chrome(service=driverService, options=option)
driver.get("https://www.google.com")
Note: The DeprecationWarning: executable_path has been deprecated is a harmless warning message which doesn't affects your test execution and you can still ignore it.

This is what I have:
from selenium import webdriver
driver = webdriver.Firefox()
How can I let the geckodriver open minimized or hidden?
You have to set the firefox driver options to headless so that it opens minimized. Here is the code to do that.
fireFoxOptions = webdriver.FirefoxOptions()
fireFoxOptions.set_headless()
driver = webdriver.Firefox(firefox_options=fireFoxOptions)
If this doesn't work for you there are other methods that you can use. Check out this other SO question for those: How to make firefox headless programmatically in Selenium with python?
geckodriver
geckodriver in it's core form is a proxy for using W3C WebDriver-compatible clients to interact with Gecko-based browsers.
This program provides the HTTP API described by the WebDriver protocol to communicate with Gecko browsers, such as Firefox. It translates calls into the Firefox remote protocol by acting as a proxy between the local- and remote ends.
So more or less it acts like a service. So the question to minimize the GeckoDriver shouldn't arise.
Minimizing Mozilla Firefox browser
The Selenium driven GeckoDriver initiated firefox Browsing Context by default opens in semi maximized mode. Perhaps while executing tests with the browsing context being minimized would be against all the best practices as Selenium may loose the focus over the Browsing Context and an exception may raise during the Test Execution.
However, Selenium's python client does have a minimize_window() method which eventually minimizes the Chrome Browsing Context effectively.
Solution
You can use the following solution:
Firefox:
from selenium import webdriver
options = webdriver.FirefoxOptions()
options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'
driver = webdriver.Firefox(firefox_options=options, executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get('https://www.google.co.in')
driver.minimize_window()
Chrome:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.co.in')
driver.minimize_window()

tl; dr
How to make firefox headless programmatically in Selenium with python?
I'm trying to implement mobile chrome crawler using python selenium.
And I want to execute mobile chrome on incognito mode.
So, I tried as below.
options = webdriver.ChromeOptions()
## run chrome on incognito mode not to use web cache.
options.add_argument("--incognito")
options.add_experimental_option('androidPackage','com.android.chrome')
driver = webdriver.Chrome(chrome_options=options)
But, mobile chrome was executed on default mode, not incognito mode.
Help me please.
The officially recommended way to launch Chrome on mobile device using Python is this:
driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities = chrome_options.to_capabilities())
See if that works for you.
This worked for me:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--incognito")
driver = webdriver.Chrome("driver path", chrome_options=chrome_options)
