Puppeteer fails to connect to Chromium on Windows 10

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 1.11.0
• Platform / OS version: Windows 10 1709
• URLs (if applicable):
• Node.js version: 10.x.x as well as 11.4.0

What steps will reproduce the problem?

const puppeteer = require("puppeteer");
puppeteer.launch();

What is the expected result? A headless browser launching in the background and no console error.

What happens instead? chrome.exe is run without any command line switch, opening a non-headless window and eventually the tab also crashes, until it is killed by Puppeteer.

I added console.log(chromeArguments) in Launcher.js just before it spawns the Chromium process -

Something makes Node.js ignore the arguments. There is no existing chrome.exe (of Chromium) active, only chrome.exe of Chrome.

Hi everyone, I’m facing the same issue. The solution provided by Phistuck doesn’t work for me.

I found the culprit. --disable-extensions is forbidden in my corporate environment. That was stupid (the extensions it mandates are not security sensitive or protective or enforcing anything). puppeteer.launch({ignoreDefaultArgs: ['--disable-extensions']}) fixes it, until the next error…
