Keeping Email Safe from the ROPEMAKER Vulnerability

This gave me flashbacks to Melissa. I was very surprised by:

Based on the security advisory, Outlook, Apple Mail, and Mozilla Thunderbird are/were vulnerable to this issue.

Da fuck? How is a CSS-based attack possible in Thunderbird? I guess not enough eyes made this dumb design patternbug shallow.

Anyhow, spread the word. Lots of our loved ones are gonna be affected by this.
