title: chrome local extension via group policy
body: <p>I wrote a small chrome extension intended for my personal using. Up until now, I've been able to load that unpacked into the dev channel of chrome without the dev mode warning of the stable/beta channels. However, this feature will be removed <a href="http://blog.chromium.org/2015/05/continuing-to-protect-chrome-users-from.html" rel="nofollow">soon</a> and I'm looking for ways to continue using this custom extension. According to the support page, it's possible via group policy, but I've been unable to do that since the extension lives locally on my hard drive and the <code>ExtensionInstallForcelist</code> in the policy requires an update url. I know I can pay the $5 reg fee  and publish the extension privately, but I do not want to pay for an extension that only I am using. Is there a way to load extension not from the chrome store into chrome, where the extension is only available locally on the hard drive? Simply loading it unpacked will give a "dev mode" warning every time chrome starts and that's annoying.</p>
