  • (2018-06-11) Nuclear Squid!!: I just discovered Mailvelope also works in NextCloud's mail plugin! Amazing. (just add your Nextcloud instance's domain to the rules for webmail providers.) Very easy to use extension for enabling end-to-end encryption. If Google *really* wanted to protect peoples' privacy this would be the way to do it. They should fund development of this plugin, drive its adaptation to all major browsers and webmail clients, and help usher in an era of end-to-end encryption where everyone's grandmother can use PGP as easily as doing a cut-and-paste :P OK I should wake up now. :/

The a webpage about maillist (chrome-extension://kajibbejlbohfaggdiogboambcijhkke/app/app.html#watchList) is open. And then? Should I choose one of the email providers? I clicked "mail.google.com" adn clicked "OK" but nothing happened next. So I don't know what to do. Would you please help me solving this problem?

    Bonjour, je suis un monsieur lambda et j'avoue que c'est pas simple, on à beau cliquer sur télécharger, ou ajouter rien ne se passe. Il faudrait faire les choses plus simple pour les novices, vous vous comprenez mais pas nous. Quand on présente un téléchargement on ne met pas mille choses qui rende le téléchargement incompréhensible. Cordialement.
