Load extensions on Windows

[ssut]

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 1.5.0
• Platform / OS version: Windows 10
• URLs (if applicable):
• Node.js version: 9

What steps will reproduce the problem?

Please include code that reproduces the issue.

I needed to load a extension that a page requires, so I added --disable-extensions-except and --load-extension args but it doesn't load on windows. The full args I passed were:

[ '--enable-logging',
  '--v=1',
  'about:blank',
  '--disable-extensions-except="C:\\Users\\...\\chrome-extensions"',
  '--load-extension="C:\\Users\\...\\chrome-extensions"' ]

And the result was:

---------------------------
Error Loading Extension
---------------------------
Failed to load extension from:
C:\Users\...\...\...\node_modules\puppeteer\.local-chromium\win64-564778\chrome-win32\"C:\Users\...\chrome-extensions". Manifest file is missing or unreadable.
---------------------------
OK
---------------------------

What is the expected result?

Load extensions properly.

What happens instead?

---------------------------
Error Loading Extension
---------------------------
Failed to load extension from:
C:\Users\...\...\...\node_modules\puppeteer\.local-chromium\win64-564778\chrome-win32\"C:\Users\...\chrome-extensions". Manifest file is missing or unreadable.
---------------------------
OK
---------------------------

I think if I pass the extension path as a relative path it might be work but I also think that is so awful.

I temporary solved this issue by removing --disable-extensions from the default arguments.

I temporary solved this issue by removing --disable-extensions from the default arguments.

This is the way to go for now; we might do a nicer extensions support eventually.

I am also unable to load my extension, I am following the same commands but instead of puppeteer I am using puppeteer-core, I do get the error saying that loading extensions is disabled by admin and the extension will not any thoughts?

Same issue with loading extension with puppeteer on windows.
Works fine on mac, though.

Getting. Manifest file missing while loading extensions.I downloaded crx file of the extension then I converted it to zip file then its relative path added. Whats wrong?

I finally fixed this exact error/issue with ublock. I had originally made several errors. It now works.

1. I had a typo in my datadir declaration
2. ublock has nested directories with weird names (I'm not sure this mattered)

Here's the working code:

	const ublock = '~/Documents/jsprojects/puppeteer-extensions/ublock/';
	const datadir = '~/Documents/jsprojects/chromeprofile/';
	const browser = await puppeteer.launch({
		headless: false,
		userDataDir: datadir,
		defaultViewport: { width:1000, height: 1080 },
		args:
		[
		`--disable-extensions-except=${ublock}`,
		`--load-extension=${ublock}`,
	});

In /puppeteer-extensions/, I changed /chromium.ublock0.152341/ or whatever to plain /ublock/, and deleted a nested sub-directory with an equally funky name. Within /ublock/ there is a manifest.json. Many extensions have multiple layers of weird-named directories. Change the dir names to something simple like /ublock/, and then make sure your line declaring the extension has that directory path typed perfectly in your code.

@Ajju2211 I think you should unzip the extension and absolute/relative path to the directory that contains manifest.json.

How about having a Chrome Web Store (CWS) extension installed and just having that not removed and not disabled and such?

[danielehrhardt]

export const extensions = [
  path.join(process.cwd(), 'plugins', 'cookies'),
  path.join(process.cwd(), 'plugins', 'ublock-origin'),
];

@danielehrhardt how did you come up with that JS? where did you find it works? can you give any more information? what version etc?
