The official way to disable the popup is this:
-
Pack your extension: go to
chrome://extensions
, check Developer mode and click Pack extension -
Install the extension by dragging and dropping the
.crx
file into thechrome://extensions
page.
You’ll get an “Unsupported extensions disabled” popup if you try restarting Chrome at this point.
Then for Windows 7 or Windows 8:
- Download Chrome group policy templates here
- Copy
[zip]\windows\admx\chrome.admx
toc:\windows\policydefinitions
- Copy
[zip]\windows\admx\[yourlanguage]\chrome.adml
toc:\windows\policydefinitions\[yourlanguage]\chrome.adml
(notc:\windows\[yourlanguage]
) - In Chrome, go to the Extensions page:
chrome://extensions
- Check Developer Mode
- Scroll down the list of disabled extensions and note the ID(s) of the extensions you want to enable.
- Click Start > Run, type
gpedit.msc
and hit enter. - Click User Configuration > Administrative Templates > Google Chrome > Extensions
- Double click Configure extension installation whitelist policy
- Select Enabled, and click Show
- In the list, enter the ID(s) of the extensions you noted in Step 7
- Click OK and restart Chrome.
That’s it!
EDIT: As of July 2018, this approach no longer works: it seems Google has stopped honouring the “whitelist”.
EDIT 2: As of December 2018, this approach works in Chrome Version 69.0.3497.100 (Official Build) (64-bit)
:
-
Temporarily enable Developer mode in
chrome://extensions
-
Uninstall the extension that causes the popup using the Load unpacked.
-
Click on Pack extension, and find and select the folder containing the extension files. Don’t enter the private key file if you don’t have it.

file will be created near the root directory of the extension. Install the extension using the.crx
file and keep the.pem
file safe. -
Copy the
.crx

The popup should be gone.
