Google+ adds a "Share" action button to custom tabs. Clicking it does not perform any action.

Same is true for Youtube. If a video has a link in the description then the custom tab will show a "Share" button but clicking it does not perform any action.

I cannot reproduce by Youtube App(ver 12.03.57). Everytime when I click link in description, it always opens a new normal tab in Fennec. (not by CustomTabIntent). But I can reproduce by G+. After inspection, invoke method `send` must give an additional intent as well. And set current URL ad data Uri to that intent. According to Android documentation[1], the method will copy information from additional-intent to original-intent if the information is missing. I gonna to get current url to invoke `Intent.setData(Uri)`, is there any best practice to get the url?

Tabs.getInstance().getSelectedTab().getURL() should give you the URL of the currently displayed website.
