Google & Facebook's login for 3rd party websites (OAuth) implementation

I need to implement OAuth for Google & Facebook in my website, such that the authentication happens in the same window (Without giving any additional popups). Now, I implemented this. But, after I clicked on "logout", I opened new tab for Google. Here, its already logging-in. "I want this auto logging-in to be prevented" Example in which I see the issue: [login to view URL] I am looking for a solution such that if I logout of my application, it will logout from Google & FB in all other tabs as well (If I open a new tab for FB/Google, it should take me to login screen first. My budget is $40 This is how I wanted this work to be done: You implement the feature & share me the link => If it works well, I award the project to you => Give me the code => I release the money
