I manually updated to 10.5.20.3 on my 770, and after the update was not able to access some websites via a Mac running MS Edge. Strange that using Safari I could access those sites, but not with Edg...

Thanks for the suggestions. After more troubleshooting, the router defaults to auto detect for IPv6. If, after disabling IPv6, and re-enable it, and select Auto Detect, it auto selects 6to4. This is when it fails. If I select Auto Config as opposed to Auto Detect, it works. Not sure exactly what that is doing as I am not greatly experienced with IPv6. From what I can tell, I don't think my ISP actually supports IPv6 yet, so not sure I even need to worry about having IPv6 turned on.
It is confusing as to why it would work on the old firmware as opposed to the new firmware. That tells me Netgear changed something in their IPv6 handling.
When I get more time I will try your suggestions, and also install Chrome to see if that works.

Who is your ISP and what is the brand and model # of the ONT your using?
Ya if you know that your ISP doesn't officially support native IPv6, then keep it disabled on the RBR. Mine doesn't and I don't have it enabled.
You could try Hurricane Electrics IPv6 service if you think you wanna check it out:
