Everything was working fine. I ran windows update on 10/31/26. Afterwards I couldn't open Firefox or Brave browsers. I've tried uninstalling and reinstalling the updates. I've uninstalled and reinstalled Firefox. I've reinstalled windows 11 three different times. There are approx. 4 programs that won't open or function at all. Nothing changes when I boot up in safe mode, or when I disable my anti virus. I've tried system restoring 4 times but it fails every time. Ironically enough, Microsoft's Edge browser operates perfectly. For some reason, if I go thru the microsoft store and choose the firefox app it downloads and works but not like it did when I downloaded it directly from mozilla. I can't make it my default browser, I can't pin it to the taskbar, and the shortcut target is the My PC folder. I've spend hours chatting with microsoft tech support. I'm at my wits end and don't know what else I can try. Any advice would be greatly appreciated.

I'm running Win.11 25h2 on an Inspiron 15-3511

My Firefox built-in VPN is stuck in an activation loop.

I am using Firefox 159.0.1 on Windows. I click "Get started", sign in successfully to my Mozilla account, and the page confirms that I am connected. However, when I reopen the VPN panel, it still shows "Get started".

I have already signed out and signed back in, restarted Firefox, and confirmed that Enterprise Policies are inactive.

Could you please check whether my Mozilla account is eligible for the built-in VPN and why activation is not being completed?

    • 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.

Firefox built-in VPN Availability

So, can somebody please explain to me why Firefox VPN is now unsupported in so many countries where people can only exercise their freedom of information by using a VPN?

Do local laws and restrictions apply to the people of these countries because of their governments' actions, while those same governments don't even need a VPN to access such information? Instead, they censor it to prevent their citizens from accessing it.

You claim to be sanctioning the "governments", but in reality, you are only sanctioning the "people" — the very people who are actually fighting against their governments' practices.
