Norton Family Issues

Hello,

I have recently upgraded my PC to Windows 10 and am trying to get Norton Family to work properly and having issues.

Issue #1

I have explicitly blocked Facebook and Twitter in the  House Rules. However, I am still able to get to them in IE (not Edge) and Firefox. Chrome seems to block just fine. I have Youtube blocked in the house rules and they block fine on all browsers.

Issue #2 

I am seeing that the Norton Family extension for Firefox is not compatible. I am using Firefox 43.0.3 and Norton Family Extension 3.4.0.45.

Let me know if there is something I can do.
