**Title: Firefox Built-in VPN suddenly unavailable

**Title: Firefox Built-in VPN suddenly unavailable – Local laws and restrictions error** Hello, I have been using Firefox's built-in VPN without any problems until yesterday. Suddenly, it stopped working and now displays this message: "VPN: Local laws and restrictions limit where you can use this feature." My system details and troubleshooting results: - Firefox version: 159.0.1 - Operating system: Windows 10 - Mozilla account: Signed in - Remote improvements: Enabled - Enterprise policies: Inactive - No relevant VPN holdback study found in about:studies. I am physically located in Tehran, Iran. However, my usual internet connection's public IP was identified as Frankfurt, Germany, by ipwho.is. I also tested using my mobile phone hotspot, which was identified as Tehran, Iran. The same VPN restriction message appeared with both connections. The built-in VPN was working until yesterday, so I would like to know whether my IP address or account has been incorrectly classified, or whether access to the service has recently changed. Could you please investigate this issue and explain why the VPN suddenly became unavailable? Thank you.
