Firefox crashes over xrdp, Chromium doesn't work.

[Lothar]

I installed "Armbian_5.25_Cubox-i_Ubuntu_xenial_default_3.14.79_desktop" because I am having many other troubles with "Armbian_5.25_Cubox-i_Ubuntu_xenial_next_4.9.7_desktop".  Everything looks working fine until I noticed I can't use firefox over a RDP, in any user session.

Also I would like to comment I can't make work chromium, getting all time a white page with a "Aw, Snap" message.

 

Any idea about how to fix these two problems?
