Hello,

You may have seen a post or received a notification regarding support for Firefox or Thunderbird with a link to another site or a phone number being posted. This is a scam and is not a method to receive support from Mozilla. Mozilla does not have telephone or email support. Please do not click on the link and do not interact by calling any phone numbers or email addresses listed. I apologize for any inconvenience caused. You are currently posting on the official Mozilla website and will receive assistance here.
