I cannot use my currently installed extensions in Google Chrome using headless mode. Is there any way to enable them?
An easy way to check if the extensions work is by adding, for example, the "Comic Sans Everything" extension.

How to run Chrome in headless mode. In order to run your tests in headless mode, you will need to use the ChromeOptions as follows. ChromeOptions options = new ChromeOptions(); options. addArguments("--headless");

Headless Chromium allows running Chromium in a headless/server environment. Expected use cases include loading web pages, extracting metadata (e.g., the DOM) and generating bitmaps from page contents -- using all the modern web platform features provided by Chromium and Blink.
You can run Chrome with extensions headless using Xvfb.
sudo dnf install xorg-x11-server-Xvfb
xvfb-run google-chrome --remote-debugging-port=9222 --disable-gpu https://www.google.comMore complicated, but it does work. It's what we use for headless chrome extension testing.

No, it's not possible, and Chrome developers decided against implementing it in any near future due to complexity of the task.
If you look at that issue you may get the idea that they are still considering it due to ChromeDriver requirements - but instead they decided to make ChromeDriver work without extensions (through DevTools).
