Developer accounts for addons.mozilla.org are integrated with Firefox Accounts, which lets you access and manage multiple Mozilla services from one account. You can manage your Firefox Account from accounts.firefox.com/settings.
Setting a display name
It’s important to set a display name on your profile on addons.mozilla.org to increase transparency with users, add-on reviewers, and the greater community.
Your Firefox Account display name will not sync to your profile on addons.mozilla.org. You will need to set your developer account display name from your profile on addons.mozilla.org.
To mitigate malicious actors from submitting spam to addons.mozilla.org, we will not accept submissions from accounts that use a disposable temporary email address, or that have submitted multiple add-ons that violate our Add-on Policies.
If you believe your account has been incorrectly blocked, please email amo-admins [at] mozilla [dot] com and include a link to your developer profile.
