Is it possible to script python3 selenium to automatically disable CSP for geckodriver?

Question

I need to disable CSP for that I can do that manually by opening Firefox() web driver, going to about:config, and disabling: security.CSP.enable.

I am new to selenium, have coded all the stuff I need to just I need to automate disabling of CSP, I don't know much about marionette, capabilities, and other details. I just want to automate the disabling of CSP. Is it possible? Is it possible by doing some capabilities changes or by doing: driver.get('about:config'); some code or by adding another extension? There may be other solutions like downloading geckodriver with no CSP, which I cant find, or maybe even compiling geckodriver with no CSP if its open source.

I cant use chromium for some reason, so I need to work with geckodriver in Linux.

This is the ugliest way, building from source code. Steps:

• Download source of Firefox: Firefox Source. Then, unzip it.
• cd/Mozilla-central-83bf4fd3b1fb/testing/geckodriver/src/ and edit prefs.rs with your favourite editor. At end write this:

// Disable CSP
("security.csp.enable", Pref::new(false)),

• Build geckodriver using cargo or mach. I used cargo build

• Load it using:

webdriver.Firefox(executable_path='./mozilla-central-83bf4fd3b1fb/testing/geckodriver/target/debug/geckodriver')

Finding docs and going through the source code and editing was quite painful as I don't know Rust. Here's the docs: Building Docs
