Hide "Navigate to this page" popup when clicking a button.

We have a Subscribe button that will take you to a different webiste when you click on it. In Lightning, when you click on the button, the Navigate to this page message will pop-up. 

Button: Subscribe 
Display Type: Detail Page Button
Behavior: Execute JavaScript
Content Source: OnClick JavaScript 

Code:'/apex/ConnectSignup?FirstName={!URLENCODE(Contact.FirstName)}&lastname={!URLENCODE(Contact.LastName) }&CompanyName={!URLENCODE(Contact.Company__c)}&email={!URLENCODE(Contact.Email)}&ContactId={!URLENCODE(Contact.CDSContact_ID__c)}');

Is it possible to add another line to prevent the pop-up from opening and take our user directly to the website?
