Stoping "Sign in with Google" Pop Ups on Safari

Like many Mac users I got frustrated at not being able to stop the annoying Google login pop ups. I read many other suggestions in posts but made no progress.

Solution: While not a perfect solution I did the following (1) I down loaded the ADGARD App (2) used their "block an element" to stop these Google login pop ups re-appearing on my regular websites I use. Its looks like the solution is web site specific - so you have to repeat the process every time you visit a new website - but after a short time given I visit the same web sites it worked! Good luck!
