ProtonMail v3.16

ProtonMail version 3.16 now offers elliptic curve cryptography, an optional link confirmation warning to guard against phishing attacks, and an “undo move” feature for those moments you accidentally send an email to the trash or the wrong folder. Link confirmation is a new security feature in ProtonMail version 3.16 that can help you identify possible phishing attacks. While link confirmation is enabled, whenever you click on a link in an email, a window first pops up asking whether you’re sure you would like to visit the URL.
