Think I may have done something wrong with my Raspberry Pi installation.

Think I may have done something wrong with my Raspberry Pi installation.
It is running on the Pi, as I can connect to it via a web browser I can load a saved workspace generate the gcode and run it.

But when I add a document I cannot highlight the document to move or resize it or drag it to create an operation.
I am using Laserweb
Frontend: 4.0.989
Backend: 4.0.96
and the browser is Firefox 54.0.1 (32-bit) ? should be 64 bit must fix that.
is it a browser problem

LW doesn’t support FF, only Chrome.

Is there a simple reason why FF does not work

We don’t want to spend time tracking down and fixing browser differences when we could be adding features or fixing bugs.
