I use KRFB 4.14.12 on KUbuntu 15.10 x64. Each time I open it (using krfb from terminal) and change the settings, if I close it, the settings are not saved. Why?

First, you must have selected "Restore manually saved session" under "System settings" -> "Startup and Shutdown" -> "Desktop session"
Then there will be an entry in the "Leave" section of the standard Plasma launcher widget, called "Save session".
