When I signed up for support.mozilla and connected my Firefox account with this page, the profile name was made of the email address I signed in. But I don't want to have part of my email address publicly in the internet. It seems that there is no way to change this. For example if the profile name is John (MozillaFan), the email address is MozillaFan@... maybe MozillaFanATgmail.com. People or bots can guess your email address and start to spam you. I would like to choose a profile name myself.

Is there a reason why the profile name is displayed like this? E.g. Is there a need to have a bracket with the email address part?
If there is no valid reason, could it be changed in order to protect the privacy better?

A SuMo member thought this is the part of the code someone would need to update:
Profile heading: https://github.com/mozilla/kitsune/blob/master/kitsune/users/jinja2/users/profile.html#L35

Thanks for any help with this!
