Deploying Chrome Extensions - Help!

p.s I am aware you can force install chrome extensions using Google Apps Admin - Which I have tried, but A. The users need to be signed into chrome for this to work, which not all our users do. and B. I would still need to use Jamf to add the intranet address to the extension, Which I have tried to do (using composer), but have had no success.

I've had success creating a custom configuration profile that will force install a chrome extension. I have not however played with setting any settings for an installed extension. You can look at the settings you can set using a configuration profile by going to this site. There is an option on that site that says you can set the new tab behavior, but it doesn't work. That site lists a bunch of other things you can manage with a configuration profile as well.

I've included an example configuration profile that you can use as a template to get started. You would create this configuration profile and upload it to the JSS. I had a hard time figuring out how to get the force install to work because you have to get the last bit of the extension URL and the chrome extension update site.

            </dict>
        </dict>
    </array>

So where I have the ExtensionInstallForceList it should look like this, the example below is the Ardusat Chrome App:
<key>ExtensionInstallForcelist</key>
<array> <string>gdclcnobolflddkbmimlehkcopmcnmfj;https://clients2.google.com/service/update2/crx</string>
</array>

From what I've read, the update site doesn't change for extensions that are downloaded from the Chrome Web Store. Again, I don't know if you can manage the actual extension from this, as I haven't tried. This would atleast get you one step closer and it doesn't require the user to be in their Google Work account. You can create this configuration profile as a computer level profile and it just get installed for everyone on that computer.
