Hello, I hope this message finds you well. I am writing to request the deactivation of my Firefox account associated with the email address stelios.polkas@ticketmaster.gr. Regrettably, I have encountered an issue with my account due to the loss of my mobile device, which contained the necessary authentication for 2FA (Two-Factor Authentication). As a result, I am currently unable to access my Firefox account or any associated services. I kindly request your assistance in disabling the 2FA authentication on my account, allowing me to regain access. Once this has been resolved, I would like to proceed with the deletion of my Firefox account altogether. Please let me know the necessary steps to complete this process and any additional information you may require from me. Thank you for your prompt attention to this matter. Your assistance is greatly appreciated.
