Changing or Deleting an Email address

Hi mbugosh, You can change the primary email address associated with your Mozilla account by adding and verifying your new email address first. To do this, visit https://accounts.firefox.com/ and sign in. Open your account settings and look for the Secondary email section. Click Add, enter your new email address, and follow the instructions to verify it. Once verified, click Make primary next to the new address. If you want to remove an old secondary email address, check your account settings for the option to remove it. Make sure your new address is verified and set as primary before removing an old address. You can find more detailed instructions in this Mozilla Support article: https://support.mozilla.org/en-US/kb/change-primary-email-address-firefox-accounts
