Hi Econoback, Sorry to hear you're having trouble signing in — I know how frustrating that can be, especially when a payment is involved. Here are a few things you can try: * Make sure you're using the correct email address associated with your Mozilla account. * Try resetting your password here: https://accounts.firefox.com/reset_password * If you're using any ad blockers or privacy extensions, try disabling them temporarily or switch to private/incognito mode. * Clearing your browser’s cookies and cache can also help. * Once you’re able to sign in, you can manage your subscription and payment details at: * https://accounts.firefox.com/subscriptions Let me know if any specific error shows up or if the issue continues. Happy to help further! — Nathan
