add extension with option headless selenium python - python

Hi i'd like to add the extension i don't care about cookies on selenium but i have this error :
selenium.common.exceptions.WebDriverException: Message: unknown error: failed to wait for extension background page to load: chrome-extension://fihnjjcciajhdojfnbdddfaoknhalnja/_generated_background_page.html
someone can help me?
Thanks
self.service = Service(self.path)
self.chrome_options = webdriver.ChromeOptions()
self.chrome_options.add_extension("tools/I-don-t-care-about-cookies.crx")
self.chrome_options.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
self.chrome_options.add_argument('--headless')
self.chrome_options.add_argument('--disable-gpu')
self.chrome_options.add_argument('--no-sandbox')
self.driver = webdriver.Chrome(service=self.service,options=self.chrome_options)```

First, install the extension in your Chrome browser, and check if it works. Then chek the correct extension location. Then you can install it when launching the chromedriver like so:
chrome_options = Options()
[...]
chrome_options.add_argument('--load-extension=/home/user/.config/chromium/Default/Extensions/cjpalhdlnbpafiamejdnhcphjbkeiagm/1.43.0_0')

Whenever I try to call driver window with the help of driver.get() function it throws error in selenium python

Whenever I type the following code, it throws an error and I am not able to connect to my driver window:
driver = webdriver.Chrome("chromedriver.exe")
Error message: InvalidArgumentException
Download chromedriver.exe
Set executable_path to the location where your chromedriver is located.
replace driver = webdriver.Chrome("chromedriver.exe") to
driver = webdriver.Chrome()
Chekc It will work or not.

Use Selenium with Brave Browser pass service object written in python

#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.

you have to set your path to brave binary.
options.setBinary("Path to brave.exe");

How to describe the path to chrome on MAC?
I used this code:
import time
from selenium import webdriver
driver = webdriver.Chrome('../chromedriver') # Optional argument, if not specified will search path.
driver.get('http://www.google.com/');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()```
I got error: **DeprecationWarning: executable_path has been deprecated, please pass in a Service object
driver = webdriver.Chrome('../chromedriver') # Optional argument, if not specified will search path.**
The "error" is just a warning; your code should work with it. Still, it is good to fix deprecation errors, because the code might stop working soon. This should not issue an error:
from selenium import webdriver
# modify if different
chrome_path = '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome'
chrome_service = webdriver.chrome.service.Service(chrome_path)
driver = webdriver.Chrome(service=chrome_service)
Of course, you can also download chromedriver. If you don't want to worry about where your Chrome or chromedriver is, you can use webdriver_manager which will automatically dowload the driver for you if necessary, and supply you with the path:
from webdriver_manager.chrome import ChromeDriverManager
chrome_path = ChromeDriverManager().install()

How to load extension within chrome driver in selenium with python

All my efforts to open chrome browser with Browsec extension enabled are failing. Here is what i tried in last -
# Configure the necessary command-line option.
options = webdriver.ChromeOptions()
options.add_argument(r'--load-
extension=C:\Users\lap0042\AppData\Local\Google\Chrome\User
Data\Default\Extensions\omghfjlpggmjjaagoclmmobgdodcjboh')
# Initalize the driver with the appropriate options.
driver = webdriver.Chrome(chrome_options=options)
driver.get("http://stackoverflow.com")
This results in error "Failed to load extension from . Manifest files is missing or unreadable"
After search for this error I get that Manifest.json file should be renamed to manifest.json.txt but doing this resulted in same error.
Any help will be highly appreciated
To open chrome browser with any extension you need to use the add_extension() method through an instance of chrome.options class and you can use the following solution :
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_extension(r'C:\path\to\extension.crx')
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()

Use this code to fetch extensions
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
ChromeOptions options = new ChromeOptions();
options.addExtensions(new File("/pathtoChromeextension.crx")); //adding
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);
Use below to get crx file
http://crxextractor.com/ from your extension id which is omghfjlpggmjjaagoclmmobgdodcjboh
Simplest answer as far as I'm aware - manifest in subfolder of location you've referenced (e.g. 3.28.2_0' or whatever the latest version of extension is...)
This assumes you're using 'options.add_argument('--load-extension=')...
For options.add_extension('reference crx file .crx')
if i understood correctly you're trying to load a local unpacked extension into selenium
in that case this code should work
options = options()
options.add_argument("--load-extension=" + unpackedExtensionPath)
a better option would be to pack your extension into a crx file
For Python you need wright path to manifest.json file
from selenium.webdriver.chrome.options import Options
from selenium import webdriver
path = os.path.dirname(r"C:\temp\mdnleldcmiljblolnjhpnblkcekpdkpa\19.5.1.10_0\manifest.json")
options = Options()
options.add_argument(f"--load-extension={path}")
driver = webdriver.Chrome(options=options)

Can I still specify a path to chromedriver using ChromeOptions in Python?

I received this error: "WebDriverException: Message: 'chromedriver' executable needs to be in PATH."
The only way I was able to fix it was to manually add one of the locations of chromedriver like this:
driver = webdriver.Chrome("/Users/anncolvin/.rvm/bin/chromedriver")
After Chrome launched, I then received this error: "You are using an unsupported command-line flag: --ignore-certifcate-errors. Stability and security will suffer."
I'd like to try using the following code to address this new error but I don't know how/if I can combine it with manually specifying chromedriver's location?
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ["ignore-
certificate-errors"])
browser = webdriver.Chrome(chrome_options=options)
browser.get("http://google.com/")
All you have to do is specify the webdriver location as an argument when calling the Chrome webdriver like so:
chrome_path = r"/Users/anncolvin/.rvm/bin/chromedriver"
browser = webdriver.Chrome(chrome_path, chrome_options=options)
