[mitproxy](https://pypi.org/project/mitmproxy/) is a popular man in the middle proxy used in web scraping operations. However, to use it for scraping `https` websites the custom certificate must be installed.

For Chrome and Chromium browsers follow these steps:

1. Install `mitmproxy` using `pip install mitmproxy` or your systems package manager like:
    - Ubuntu: `sudo apt install mitmproxy`
    - MacOs: `brew install mitmproxy`
    - Windows: download binary from mitmproxy.org
2. Run `mitmproxy` in the terminal and it'll start a proxy on `localhost:8080` on your machine.
3. Start Chrome instance with `mitmproxy` proxy attached to it:
    - Linux: `google-chrome --proxy-server="localhost:8080"`
    - MacOs: `open -a "Google Chrome" --args --proxy-server="localhost:8080"`
    - Windows: `chrome.exe --proxy-server="localhost:8080"`
4. Open `http://mitm.it` in the browser and download the certificate for your system.
5. Install the certificate to your Chrome or Chromium browser:
    1. Open `chrome://settings/certificates` in the browser.
    2. Click on `Authorities` tab.
    3. Click on `Import` button and select the certificate from the step 4.



Now `mitmproxy` will be able to intercept and decrypt all `https` traffic going through it. This enables it being used with headless browser tools like Selenium, Playwright or Puppeteer.
