Firefox block planet vpn now?

For some reason, the VPN extensiond oesn’t work anymore when it did perfectly before, why?

Thanks for your answers, I really need a vpn to access some site

When an extension stops working properly, please go to its download page and use the “Support site” or “Support email” links to notify its developer(s).

The only free and reliable VPN is ProtonVPN. Also you should not use its browser extension, it’s not as good as the desktop app
