title: addons for Firefox for Android - Disable menu item?
body: <p>I've looked at the <a href="https://developer.mozilla.org/en-US/docs/Extensions/Mobile/Creating_a_User_Interface" rel="nofollow">documentation</a> and the <a href="https://github.com/mfinkle/skeleton-addon-fxandroid/blob/master/bootstrap.js" rel="nofollow">example</a> but it only shows ways to add/remove menu items, but not disable. Is it not possible or is there a way to do this? If so, can you please provide me a link to the full API(if there is one).</p>
