Been using Netscape then Mozilla load since 1996. Jan 13 2025 I turned on computer (for 3rd time) and (all browsers) Mozilla is blocked by windows defender firewall. Jan 14th I turned on PC and same.

Setting\windows defender firewall setting is now in perpetual circle of processing request.

  • Windows Smart App Contol is turned off.
  • advance virus scan will not launch due to alpha characters will not populate, only numeric, even when switching keyboard languages.
  • quick and full scan work with no errors, prior successful was Jan 10th , 10 min before turning off computer (quick)
  • no error or alarms other than "firewall is blocking Mozilla & Mozilla VPN". MS Edge Browser just sits with no pages loaded, no error messages.
  • NIC and internet is working fine as ping and othe CMD to international work. Email clients work.
  • Client ( L&T TS) Microsoft Intune installed for work Account

Windows 11 pro, all updates to windows and Mozilla, virus and dell processed through January 10 (from history)

If all browsers are affected then it's a OS issue and you need to contact windows support.
