selenium in python, how to ignore errors without closing the browser

I'm doing an automation using Selenium in Python
How could I simply ignore an error that happens on the site without it closing the browser?
I looked in several places about and I didn't find anything that helped me

You can do:
# Needed libs
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_experimental_option("detach", True)
driver = webdriver.Chrome(options=chrome_options)
Then, if something fails, your browser will not be closed.

Prevent Selenium from taking the focus to the opened window

I have 40 Python unit tests and each of them open a Selenium driver as they are separate files and cannot share the same driver.
from selenium import webdriver
webdriver.Firefox()
The above commands will take the focus to the new opened window. For example, if I am on my editor and typing something, in the middle of my work, suddenly a selenium browser is opening and Linux switch to that window. I am not sure if Windows or Mac have a similar problem or not.
This means that every time I run a unit, I cannot use my computer as it keeps switching away from the application that I am currently using.
How can I tell Selenium not to switch to the opened window?

Here is an example of running Selenium/Firefox on linux, in headless mode. You can see various imports as well - gonna leave them there. Browser will start in headless mode, will go to ddg page and print out the page source, then quit.
from selenium.common.exceptions import NoSuchElementException, TimeoutException
from selenium import webdriver
from selenium.webdriver.firefox.service import Service
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options as Firefox_Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support.ui import Select
from selenium.webdriver.support import expected_conditions as EC
firefox_options = Firefox_Options()
firefox_options.add_argument("--width=1280")
firefox_options.add_argument("--height=720")
firefox_options.headless = True
driverService = Service('chromedriver/geckodriver') ## path where geckodriver is
browser = webdriver.Firefox(service=driverService, options=firefox_options)
wait = WebDriverWait(browser, 20)
browser.get('https://duckduckgo.com')
print(browser.page_source)
browser.quit()
Browser can also take screenshots while in headless mode, if any unit test requires it.
A reasonably well structured documentation for Selenium can be found at https://www.selenium.dev/documentation/ (with some gaps, of course, but generally decent).

You can run your Selenium drivers in headless mode. This will prevent moving focus on opened by Selenium browsers and will not disturb you working on your PC machine.

Selenium: Follow adfly redirect

Im trying to make a bot that visits my adfly link using the chrome webdriver. Every time I try to use the code below though, the webdriver tells me that there were too many redirects and doesn't follow through. The code below is just being used for testing at the moment:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--proxy-server="+"http://102.129.249.120:8080")
browser = webdriver.Chrome(options=options)
browser.get("http://raboninco.com/18Whc")
Image of error here

Okay so i figured it out. I can use tor with selenium to get access to adfly. Works great btw. Thanks for the help and time guys. If you want to see the code I used, here it is:
from selenium import webdriver
import os
os.popen(r'C:\Users\joldb\Desktop\Tor Browser\Browser\TorBrowser\Tor\tor.exe')
options = webdriver.ChromeOptions()
options.add_argument("--proxy-server="+"socks5://127.0.0.1:9050")
browser = webdriver.Chrome(options=options)
browser.get("http://raboninco.com/18Whc")

Chrome opens with “Data;” with selenium chromedriver

Trying to open "Google" or any other page (website) from Chrome via selenium chrome driver in python.
The code is :
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
import time
driver = webdriver.Chrome()
driver.get('https://google.com')
However, this opens my chrome window with the specified link and "data;" tab.
Why that data; tab opens? How to fix it?
Using latest versions of Chrome and Chromedriver

You don't need as much module for this just remove all of those apart from:
from selenium import webdriver
And try again you will not get another tab with congaing data.

import time
time.sleep(1)
driver.switch_to.window(driver.window_handles[1])
driver.close()
driver.switch_to.window(driver.window_handles[0])
time.sleep(1)

I'm not sure if its the same problem, but some time ago I made an exe script to run in another PCs and in one of the PCs selenium just didn't worked with Chrome.
This is the question I posted, but the answers didn't help me, hope it works with you: Chromedriver do not open a new session, it opens a new tab in a existing session
If it doesn't work, I made a workaround to run with Firefox instead of Chrome to ensure it would work properly.

With selenium 4 (or newer), you can use the following code to launch a new browser, (without the Chrome is being controlled message), and then the browser navigates to Google in the same tab:
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option("useAutomationExtension", False)
service = ChromeService()
driver = webdriver.Chrome(service=service, options=options)
driver.get('https://google.com')

Full screen Firefox Python Selenium

I'm trying to start a full screen page in Firefox with Selenium in Python 3. The page opening works fine, but when I send the F11 key to the browser (the Full Screen key), anything happens. Here is my code :
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
firefox = webdriver.Firefox()
firefox.get('http://localhost')
firefox.maximize_window()
body = firefox.find_element_by_tag_name('html')
body.send_keys(Keys.F11)
Does anyone know how to make my page start in full screen ? I know it's possible with Chrome, but it's harder with Firefox

This is what worked for me.
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get('http://localhost')
driver.find_element_by_xpath('/html/body').send_keys(Keys.F11)
Hope this helps
Just realized I am using Python 2.6 vs your 3. Sorry about that, but at least you know it will work on an older Python version

Selenium has a built-in method to make the window fullscreen: fullscreen_window()
Selenium API - fullscreen_window()
Invokes the window manager-specific ‘full screen’ operation
browser.get("https://www.screenku.com")
browser.fullscreen_window()

pip3 install selenium pyautogui
#!/usr/bin/env python3
import pyautogui
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("dom.webnotifications.enabled", False)
profile.set_preference("general.useragent.override", "Mozilla/5.0")
profile.update_preferences()
browser = webdriver.Firefox(firefox_profile=profile,executable_path = '/usr/local/bin/geckodriver')
browser.get("https://www.screenku.com")
pyautogui.press('f11')
