Selenium + Python | QA Automating

I am automating some QA processes and I have some doubts along the way that do not allow me to move forward.
I have the following problems:
I need that when I open the Chromewebdriver, it automatically chooses the tab I want from the devtools, being Elements, Console, Recorder, Sources, etc.
What I could do so far is, when the browser is running, that the DevTools is open, but in its main tab, that would be elements
Extract information from the values of an extension (Is this possible?) The extension appears in the DevTools.
To add a kind of alert that does not allow you to advance if you do not click.
Take a screenshot (I could do this, but only the web page appears, and I would need that it appears besides the web, the DevTools).

Easy way to work around slow Selenium Python startup?

So I have a program I want to run using selenium specifically that takes a series of actions on a password-protected website. Basically, I need to be able to input a unique link and password when I get it, which will take me to the main website which I have automated. The issue here is that Selenium takes very long to get to load a webpage when you start it up and time is very important in this application. Inputting the link and launching the browser to that link directly takes a long time. What I have tried doing is preloading the browser to a different website (ie, https://google.com) beforehand, and then waiting on user input for the link to the actual page. This process works a lot quicker, but I'm having trouble getting it to work inside a function and with multiprocessing. I am using multiprocessing to execute this on a wide scale with lots of instances. I am trying to start all of my functions the second a link is defined by me. I am on Windows 10, using Python 3.8.3, and using Chrome for my Selenium browser.
from selenium import webdriver
global link
link = input('Paste Link Here: ')
def instance_1():
browser1 = webdriver.Chrome(*my webdriver file path*)
browser1.get('https://google.com')
#need something that waits here until the link variable is defined by me
browser1.get(link)
#the rest of the automation works fine from here
Ideally, the solution would be able to work with multiprocessing. The ideal flow would be something like this:
1. All selenium instances" (written as their own functions) start-up and preload to a website (this part works fine)
2. They wait until the link to go to is specified (this is where the issue is)
3. They then go to the link and execute the automation (this part works fine)
Tldr; basically anything that would allow me to let the program continue while waiting on the input would be nice.

Take a screenshot of an entire webpage using Robot Framework

I have a problem on taking a screenshot using robotframework.
Currently I am using keyword Capture Page Screenshot on Selenium2library. The problem is that, keyword only captures the webpage visible on the screen.
We needed a screenshot that could take the entire webpage. This means that when it capture a screenshot it should scroll down to the bottom of the webpage and capture the whole page. Is that possible?
Appreciate everyone can suggest if there are other library that we can use.

You can do that with a headless browser:
http://phantomjs.org/
Execute it from Python as a separate process if you need to, storing the result into a file.

Selenium: Testing pop-up windows

I have an issue when trying to test a web application with Selenium/Python. Basically I can't test elements of a pop-up window.
A scenario: I can test all elements for a page. But when I go to click on a button that opens up a small pop up box I can't test the elements on the popup. It's like the pop up isn't in focus or active.
I can test elements on the next page. For example click a button, brings me on to next page, and I can work with elements on the 'next' page. So it the problem seems to be popup specific.
I could post code but to be honest it might confuse at this stage. I may post code in a later post, thanks

There is a property called switch_to
Q: How do I handle pop up windows?
A: WebDriver offers the ability to cope with multiple windows. This is done by using the WebDriver.switch_to.window(knownName) method to switch to a window with a known name.
If the name is not known, you can use WebDriver.window_handles to obtain a list of known windows.
You may pass the handle to switch_to.window(handleName)
For example I used driverName.switchTo.window(driverName.getWindowHandle()) to get a hold of popups for which I didn't want to look for names.

For the Selenium RC API, you need to use the SelectWindow command to switch to the pop-up window. The window can be specified either by its name (as specified on the JavaScript window.open() function) or its title. To switch back to the main window, use SelectWindow(None).

Can I Use Python to Make a Delete Button in a 'web page'

I have written a script that goes through a bunch of files and snips out a portion of the files for further processing. The script creates a new directory and creates new files for each snip that is taken out. I have to now evaluate each of the files that were created to see if it is what I needed. The script also creates an html index file with links to each of the snips. So I can click the hyperlink to see the file, make a note in a spreadsheet to indicate if the file is correct or not and then use the back button in the browser to take me back to the index list.
I was sitting here wondering if I could somehow create a delete button in the browser next to the hyperlink. My thought is I would click the hyperlink, make a judgment about the file and if it is not one I want to keep then when I get back to the main page I just press the delete button and it is gone from the directory.
Does anyone have any idea if this is possible. I am writing this in python but clearly the issue is is there a way to create an htm file with a delete button-I would just use Python to write the commands for the deletion button.

You could make this even simpler by making it all happen in one main page. Instead of having a list of hyperlinks, just have the main page have one frame that loads one of the autocreated pages in it. Put a couple of buttons at the bottom - a "Keep this page" and a "Delete this page." When you click either button, the main page refreshes, this time with the next autocreated page in the frame.
You could make this as a cgi script in your favorite scripting language. You can't just do this in html because an html page only does stuff client-side, and you can only delete files server-side. You will probably need as cgi args the page to show in the frame, and the last page you viewed if the button click was a "delete".

You would have to write the web page in Python. There are many Python web frameworks out there (e.g. Django) that are easy to work with. You could convert your entire scripting framework to a web application that has a worker thread going and crawling through html pages, saving them to a particular location, indexing them for you to see and providing a delete button that calls the system's delete function on the particular file.

Rather than having your script output static HTML files, with a little amount of work you could probably adapt your script to run as a small web application with the help of something like web.py.
You would start your script and point a browser at http://localhost:8080, for instance. The web browser would be your user interface.
To achieve the 'delete' functionality, all you need to do is write some Python that gets executed when a form is submitted to actually perform the deletion.

Well I finally found an answer that achieved what I wanted-I did not want to learn a new language-Python is hard enough given my lack or experience
def OnDelete(self, event):
assert self.current, "invalid delete operation"
try:
os.remove(os.path.join(self.cwd, self.current))
