Unable to open new tab msg

[AC Question]

Got this MSG from the browser on my galaxy grand prime phone. I have closed the tabs within Chrome but I still get this msg when using the browser and it does not open the page I seek. Samsung tech agents only tell me how to avoid the error and get to the page I'm seeking but not how to stop the error. I've consulted Samsung support twice but I still get the error msg when using the browser. It's frustrating! Please help!!!
