“Chrome extension throws CRX file Error ”CRX_REQUIRD_PROOF_MISSING"

Question

I have Chrome extension and create the crx file using developer mode. I uploaded the crx file to some internal url (www.xyz.com/internal.crx).

Answer 1

As of December 2020. Only 4 possible option to install extension.

1. Get a signed CRX file from Google web store.

2. Use Chromium to install CRX file in developer mode.

3. Import extension's directory as unpacked extension.

4. Modify/Configure ExtensionSettings policy as in documented here.

I preferred option 2, as I am a private person. And option 4 in enterprise settings.

In some cases it is not advisable or not feasible to submit the browser extension for Google certification.
