Hi

This does not sound like an issue with Firefox, but is something that you would need to address with that site seperately. I can recomend not unsubcribing to spam as (unlike legitimate promotional email) it can often prompt more junk mail to be sent to you.

Some e-mail providers have the option to sort incoming mail. Contact your e-mail provider for help.

The spam started with using the firefox option to synchronize your browsing across multiple devices by creating a firefox account.

That makes this a firefox issue.

I am not making fun of you or denigrating you in anyway, but the Do Not Call registry is less useful than mammary glands on a warthog.

My phone is on that list and I get 10 to 20 cranks a week.
