We previously had an add-on/extension of ours listed on the Firefox marketplace: https://addons.mozilla.org/en-US/firefox/addon/sign-in-gmail/ Since that time we've been self-hosting the extension with regular updates, but now due to add-on signing (https://support.mozilla.org/en-US/kb/add-on-signing-in-firefox) we are looking to distribute our extension via the Firefox marketplace again. I haven't had any success in finding which account is associated with this extension and would love some help in either transferring that extension to this account or getting help accessing the existing account it's under (even an email address is a great start). This would help us maintain our image and branding on the Firefox marketplace. Thanks in advance!
