Not compatible applications
With JonDonym not compatible applications
This add-on leaks DNS requests. We therefore do not recommend using FireFTP with JonDonym.
NetObjectsFusion is a web development tool. It can not use a proxy for uploading your web pages to a server. Please export your web pages to a local directory and use a compatible application for anonymous file upload.
E-mail clients Evolution and KMail
It is not possible to configure a SOCKS proxy for Evolution (GNOME desktop mailer app) and KMail (KDE desktop mailer app). Both can not be used for anonymous mail accounts with JonDonym.
