K9 is a near perfect email client.
All Mozilla did was take an existing privacy respecting app (with zero user tracking) and add their spyware telemetry code to it: 544mozilla.telemetry.glean.
Now they are gas lighting users by advertising this new version as “privacy-focused”.
Mozilla is like a virus at this point.
Honestly I wish those developers would focus on the basics rather than esoteric input devices.
KDE isn’t stable enough with a regular mouse and keyboard, let alone fancy input devices. It crashes WAY too often and has too many bugs which require the user to constantly have to use the terminal to work around.
KDE: get your priorities straight and focus on basic stability and usability first.
