I signed up for a Firefox account and everyday I am getting at least 1 mail from Firefox. I have clicked on "Unsubscribe" link and even checked the last checkbox to unsubscribe from everything. It does say that it might take a week for the setting to take effect. It's been almost a week. And I am still getting mails.
Has anyone faced similar issue? Could you resolve it?
Are you by any chance living in the EU and can use GDPR (data protection regulations) as lever against the sender to stop it ?
