Firefox browser has stopped opening websites on my Dell laptop. Get "secure connection failed" error message. Other browsers work just fine. I have refreshed, uninstalled and reinstalled Firefox from both firefox website (using Brave browser) and from MSN store.

Whenever i try to connect to any site, it fails to load and displays the following error message:

This web site requires a secure connection. - The page you are trying to view cannot be shown because this web site requires a secure connection. - The issue is most likely with the web site, and there is nothing you can do to resolve it. - You can notify the web site’s administrator about the problem.

When i press 'advanced' it says: [Site name] has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

This happens on every site i try to visit. I am on a samsung phone running android version 15. Other browsers do not have this problem (i am sending this from opera), and firefox works fine on my other devices.

I am running windows 11. I routinely use firefox to access wireclub.com. Two days ago I started getting the following error:

We encountered a problem when completing your request.

We have been notified and are attempting to fix the problem as quickly as possible.

I tried clearing my cache that did not work. All other sites other than wireclub.com are working fine. I can access wireclub.com with Microsoft edge no problem. Any suggestions
