I want to deploy a Chrome extension hosted on Chrome store.
According to:
http://developer.chrome.com/extensions/external_extensions.html
I need to include a CRX file, so how do I get it from the Chrome store?
I can't pack it using my own *.PEM key since it won't install and the key differs from the one generated on the Chrome store.
So, please, how do I deploy it?
The whole content of the crx is landing in the chrome directory, more specifically:
c:\Users\USERNAME\AppData\Local\Google\Chrome\User
Data\Default\Extensions\
All installed extensions are listed here by their ID's.

I'm building an internal extension for my company. Since it's an internal tool, I don't want to publish it on the Chrome Web Store.
To be able to self-host the browser extension, I'm doing the following steps:
(before): I created a .pem to sign the extension (+ keep a constant extension id across updates)
I'm building the source code
I'm packing and signing the extension with chrome using chromium --pack-extension=./build_dir/ --pack-extension-key=./key.pem
I'm updating the update.xml file to reflect the new version number
I uploaded the signed .crx and update.xml
I have a website with a link pointing to the .crx file. The issue is the following: when clicking on it, the file is downloaded and chrome understands it's a browser extension. Then: I'm getting "Package is invalid crx_required_proof_missing".
What am I missing?
What can I do to be able to install a self-hosted extension after downloading the extension?
Notes:
I am aware that I can extract the .crx content and load the extension as "unpacked", but that's not what I'm looking for: deployment will be more complex (more manual steps) and updates will not be automatic.
The .crx file seems to be served with the right headers and is publically accessible. The update file is also correct and accessible.
Info:
Yes, the manifest contains properties key and update_url.
When dragging/dropping the .crx file in chrome://extensions (in dev mode): the extension is installed but I'm getting a red warning on the extension card: "This extension is not listed in the Chrome Web Store and may have been added without your knowledge"
When dragging/dropping the .crx file in chrome://extensions (without dev mode):
The extension is not installed and I'm getting: "Package is invalid crx_required_proof_missing".
When dragging/dropping the .crx file in chrome://extensions (with CHROMIUM and dev mode):
The extension is properly installed and working.
I try to auto-install a chrome extension on a WIN10 device that have no connection to the internet and thus can not access the Chrome Web Store. So uploading the extension to the CWS is no option. The extension exists as a crx file on a server in a network and on the device.
On Chrome Versions 59 and lower I could install the extension via settings in the registry. When Chrome was started, the user was ask if he wants to install the extension.
For this I used the registry key ExtensionInstallWhitelist and defined the path and version of the extension under the key "[...]/Google/Chrome/Extensions/[ExtensionID]".
But since Version 60 the extension does not appear in Chrome anymore. So I tried to auto-install the extension via an Active Directory domain policy.
I have imported the chrome policy templates and configured the entry ExtensionInstallForcelist (http://www.chromium.org/administrators/policy-list-3#ExtensionInstallForcelist) in the group policy editor. This policy setting is listed on the chrome://policy page in Chrome. But the extension does not appear in Chrome. The ExtensionInstallForcelist entry contains "[ExtensionID];[url where the crx file resides]". I also tested this with an url to an "Update Manifest XML document" which points to the crx file. Neither of them worked.
Does anyone know, if Chrome 60+ still supports this?
Is my configuration incorrect?
Any help will be appreciated, thanks!
Background:
I manage an offline network of workstations.
I have written a chrome extension that needs to be in the browser for our webapp to function
I have published it through the chrome store (but not made it public)
Question:
How do I install this extension without the internet
What I've tried:
Windows GPO: Requires the update URL to be http://clients2.google.com/service/update2/crx
Windows Registry: same URL problem
Unpacked extensions: prompts users, requires developer tools, and disables the extension when chrome is restarted.
install crx: disables the extension when chrome is restarted.
Any other ideas, or ways around this?
Chrome version 48.
I was able to do this on a regular chrome installation by doing the following:
Download the extension in crx format - how to download a crx file from the chrome web store for a given id
Unzip the crx file
I had to rename the _metadata folder to metadata
Open the chrome extensions page
Enable Developer mode
Click "Load unpacked extension..."
Select the unzipped folder
This worked for me when I needed to install Advanced REST client.
I have just:
Downloaded the add-on CRX file using http://crxextractor.com/
Opened the "extensions" page on Chrome.
Drag-and-dropped the CRX file onto the "extensions" page.
I got it to work actually, sadly forgot about this post until now.
I had the Business version installed as #gerardnimo suggested.
What I wound up doing is
1) setup and IIS server to serve both the CRX and the update xml. based on this guide. https://developer.chrome.com/extensions/autoupdate
2) Then i was able to install the extension via group policy.
Here is a thread that I've found. He suggests that you can use Google Chrome for Business.
Since September 3, 2015, Installing Chrome extensions off-line no longer work (and here ) due to Google trying to prevent malicious extensions being downloaded and installed. To install an extension off-line today, require you to install a signed pre-packaged full Chrome install, using Googles Chrome for Business. This functionality is controlled by a policy list. Or according to this post, you can use their Dev or Canary channels to run any extension. Their latest builds can be found here
We built a chrome extension to be used only inside our company by selective people. We do not want to publish this on chrome web store. We could do this before by just drag & drop the crx file in the extensions page.
But in the latest version of chrome(i use 35.x), we are not able to do this anymore. Whenever we try to install the crx file, chrome automatically disables it and shows a message
"This extension is not listed in the Chrome Web Store and may have been added without your knowledge"
with a link to https://support.google.com/chrome/answer/2811969 where it says
"You're seeing this notification because one or more of your Chrome extensions has been turned off to make Chrome safer. The extensions didn't come from the Chrome Web Store or were installed without your permission."
So, Does this mean we can never install crx file from now on? No workaround?
I know we can install using Group Policy method, but is that the only way we can do this?
Thanks in advance.
Yes, this has been disabled as a protection against malware.
The only workarounds I'm aware of are:
turn on Developer Mode and have users install as an unpacked extension after unzipping the CRX
publish unlisted or to a Google Group: https://support.google.com/chrome/a/answer/2663860?hl=en
I have uploaded a chrome extension on webstore but lost the local from my desktop. Is there any way to download the extension back either from webstore or developer dashboard such that I get all my files?
Just install it and then go to your User Data directory.....
http://www.chromium.org/user-experience/user-data-directory
..then into the directory of the profile you installed it under, then the extensions directory and then the directory with the key of your extension, then the directory with the latest version and youll find all your files. You can find the key listed on the extension page in chrome in developer mode. Dont forget to edit the manifest, remove the update url and such.
Or if your on windows (I know it works in XP, never tested vista/7) you can use my convenience tool ExtensionOpener.....
