How to start selenium chromedriver script with already opened profile in chrome

I'm using selenium chromedriver with Google Chrome profiles on Mac OS and Windows. As I understand it, in the usual case the selenium script will not work if another profile in Google Chrome is open. This causes some inconvenience as a regular google chrome user - every time before I run the script I have to close the browser completely.
I would not be comfortable switching to the gecko driver because firefox does not allow me to install the extensions I need. Are there any other options on how to solve this problem?

How to scrape without web browser driver?

I made a web scrape program using selenium.
This program is access target URL and download a file.
After updating Chrome, program does not work because chromedriver is old version.
How to do web scraping and file download not use chromedriver?
Thank all for reading.

I think it would be easier if you also updated ChromeDriver, that way your program would work again. Or you could install the previous Chrome version again.
But if you don't want that, you can use GeckoDriver with Firefox.

You can use a headless scrapper like Pupeppeteer. You also can update your Chrome driver to be compatible with your browser version that is the most recomended.

Using Chrome Addons in a Selenium Session possible?

For a project of mine I decided to go with Selenium. It's a "scanner" for an web based online game, hence interaction with the page is needed. All things set and done I'm worrying for the security of my application and hence I took a look at well-known questions on SO. I found bunch of suggestions which may help securing the detectability of said programme.
What is left is something related to Chrome Plugins. In my Project File I got the chromedriver.exe and a dedicated resource folder for stuff like the cookies and settings it's supposed to run with. Now I want to run the Chromedriver.exe with Chrome Plugins.
So is there any way to download Chrome Plugins in the Chromedriver.exe and run them every time with the Selenium process?

First method is to create a chrome profile and load it with youre chrome plugins
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Path") #Path to your chrome profile
w = webdriver.Chrome(executable_path="C:\\Users\\chromedriver.exe",
chrome_options=options)
Read more here How to load default profile in chrome using Python Selenium Webdriver?
another method is to add it in the chrome options:
options.add_extension('./exampleOfExtensionDownloadedToFolder.crx')

To download the chrome extension, follow below steps.
add chrome extension.
Go to http://chrome://extensions/]
Enable developer mode.
Click on 'Details' of desired extension.
Click on 'Pack Extension'.
Browse extension root directory. Eg. C:\Users\Admin\AppData\Local\Google\Chrome\User Data\Default\Extensions\mooikfkahbdckldjjndioackbalphokd\3.17.0_0 ( Don't forget to sort the folders by date and select latest folder.)
Click on 'Pack Extension'.( If any error get encountered related to key browse manifest.json file from step 6 path)
Browse to extension path (Eg. C:\Users\Admin\AppData\Local\Google\Chrome\User Data\Default\Extensions\mooikfkahbdckldjjndioackbalphokd ) you will find .crx and .pem file.
Copy and paste both the files in resources folder of your project.
Below java code will help you to access the extension.
System.setProperty("webdriver.chrome.driver",
System.getProperty("user.dir") + "\\src\\test\\resources\\executables\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addExtensions(new File(System.getProperty("user.dir") + "\\src\\test\\resources\\executables\\5.6_0.crx"));
options.addArguments("start-maximized");
WebDriver driver = new ChromeDriver(options);

What modules are best to imitate selenium style of being able to login into accounts and place orders? Without opening web browser [duplicate]

I have been trying to do web automation using Selenium. Is there any way to use a browser like Chrome or Firefox without actually installing them, like using some alternate options, or having portable versions of them. If I can use portable versions how do I tell Selenium to use it?

To use the browsers like google-chrome and firefox you have to install the full-blown browser.
You can find a detailed discussion in Is Chrome installation needed or only chromedriver when using Selenium?
As an alternative you can use the headless phantomjs browser as follows:
Code Block:
from selenium import webdriver
driver = webdriver.PhantomJS(executable_path=r'C:\WebDrivers\phantomjs.exe', service_args=['--ignore-ssl-errors=true', '--ssl-protocol=tslv1.0'])
driver.set_window_size(1920, 1080)
driver.get("https://account.booking.com/register?op_token=EgVvYXV0aCJ7ChQ2Wjcyb0hPZDM2Tm43emszcGlyaBIJYXV0aG9yaXplGhpodHRwczovL2FkbWluLmJvb2tpbmcuY29tLyo2eyJwYWdlIjoiL3JlZGlyZWN0LXRvLWpvaW5hcHAtbHA_bGFuZz1pdCZhaWQ9MTE4NzM2MCJ9QgRjb2RlKg4QAToAQgBY5dGK8gVgAQ")
print(driver.page_source)
driver.quit()

Do headless web browser need selenium WebDriver?

Install Selenium typing pip install selenium.
It comes with a portable version of Chrome browser, no need to manually install any browser for this.
Chrome will show this message to indicate that it is being 'remote controlled:

Checking current browser url with python

I'm trying to make an app that blocks some acces to certain websites, now i'm stuck thinking how to check the current url. I've tried selenium, but that doesn't work when you change tabs, so i had to try something else. I've been thinking about a chrome addon that checks current url and sends it to my python code, but i don't know how to do it without making any additional server. Any help appreciated.

You can use selenium and web drive manager for this
Install webdrive manager first using
pip install webdrive-manager
Then input the following code
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())
print (driver.current_url)
