You might remember, back in December, 2015, Mozilla put Thunderbird up for adoption, saying it considered the popular email client too draining, both in terms of developer time and finances. Back then, some wondered if the main reason was because email clients aren’t sexy enough in a day and age when most consumers are using web-based email — which might be closer to the truth than Mozilla is willing to admit. Be that as it may, plenty of people — myself included — still rely on local email clients, for privacy reasons if nothing else.
