Switch to window (tab) without bringing browser to front

I am using Python and Selenium to navigate multiple tabs. How can I switch to a different window/tab without bringing the entire browser window to the front and without the selenium window "stealing" the focus of my computer? For example, if I'm typing in the search bar of a normal browser and my script switches tabs, it'll stop typing the search bar and I'll have to reclick the search bar to start typing again.
No headless mode suggestions please.
Changing the browser location off the screen doesn't work because it still steals focus
Minimizing the browser doesn't work because it unminimizes when the switch to command is run
Here is how I'm switching windows:
for handle in driver.window_handles:
driver.switch_to.window(handle)
The answer is NO, this is not possible to do with Selenium.
Selenium is created to simulate actions a user can do via GUI.
As a user you can't do what you are asking about, Selenium can't do it as well.
I think, If you deploy your Automation scripts to a VM (which is there in you Machine), You can continue to start working on your local browser and Your Automation script will run on a VM and will have a independent environment for the same.

Activating / clicking a browser extension in Firefox with Selenium in Python 3

I am writing a script for web automation with SELENIUM and, in theory, I have two options to capture the data I need from the websites I am scraping:
I can let the script extract relevant information from each tag on the result pages.
I can make the script click on the browser extension button in my browser window and let the extension manage the data for me.
I know how to extract information by HTML tag, but when it comes to browser extensions, I have only found instructions how to install / uninstall them with SELENIUM, but no instructions how to "activate" them once they are installed.
I am using Firefox and would be very grateful if you could point me in the right direction.
I was not able to solve this problem in FIREFOX but in CHROME:
I created a browser profile including my extension and a key shortcut to activate it.
I opened that profile when starting the browser with SELENIUM.
I used SELENIUM to navigate to the right URL.
I used pyautogui to press the relevant keys and trigger the file download.

Download file with Selenium, Python 3

How can I download a file opened with a blob link via Selenium Chrome? Selenium chrome window shows the player on a black background. I am interested in downloading only with selenium. I use Python 3.6.

Selenium cannot work unless there is a web page to insert itself into. Once there is no page, nothing can be automated. Maybe a right-click would be needed here and then maybe a robot for automating outside of the page code.

Is there a way to access chrome extension background pages on Cypress?

I'm interested in seeing the network tab in an extension's background page while running tests using Cypress.
When I go to chrome://extensions and click background page within the Cypress browser nothing pops up. I've also tried navigating directly to chrome-extension://(extension-id)/_generated_background_page.html but this stops the extension from working entirely.

launch chrome extension from command line

I have created a chrome extension which opens a new tab window,plays youtube videos and collects the network statistics.
What I currently do is to launch the chrome and then click the extension icon to run the extension. Now I want to automate the process of launching chrome and the extension simultaneously from command line.
Please guide me how I can open and run the extension on chrome from command line.
I have tried --load-and-launch-app and --load-extension.
You can move the logic of your extension in your background.js page. In this way when chrome starts, it will run your code in background.js without clicking extension icon.
For starting chrome use -
start chrome
