Norton secure browser

What can someone tell me about the norton secure browser? I keep getting a pop up to install it.

What is the benefit. I have no security problems. I already have chrome and Edge on my laptop. I have  Norton 360 which has worked great for  me thus far.

Is this legit or a scam. I just read here that someone googled to learn more about this so called browser and found nothing.

Ideas, opinion? What does the Norton Secure Browser offer if it's real that I need and don't have.Thanks
