Turn buttons to able to be clicked with middle mouse buttons

I want to turn buttons like the following to be clickable by the middle mouse button so it will be possible to open them in new tabs.

These buttons are on Aliexpress' orders page:

<button button_action="confirmOrderReceived" orderid="87428853391079" type="button" data-order-status="WAIT_BUYER_ACCEPT_GOODS" data-order-biztype="AE_COMMON" class="ui-button ui-button-normal button-confirmOrderReceived">
                    Confirm Goods Received
                 </button>

I tried to turn them into a but then they aren't clickable.

These don't work either: http://ift.tt/2ApqbqA

Is there another way to inject a script that will turn all the buttons on a page to be tab clickable?
