This is probably because the netsurf process has insufficient permissions to access the device. Try running as root. If that fixes the issue, changing /dev/input/mouse to be readable by the netsurf process should be an OK temporary fix.

To be clear I don't think this is a netsurf issue - this needs to be fixed with a (say) udev rule or group membership change.

I just compiled 3.7 version with TARGET=framebuffer and run nsfb with sudo at non-X console. Now I have slighly different message:

Message translations failed to load.
Unable to set video: Couldn't set console screen info.
Unable to initialize framebuffer.

The message about the mouse is gone, but now something is wrong with screen info.

Some additional information which may be usefull.

As a comparison, I opened video with mplayer in non-X console with '-vo fbdev' option. It didn't played with following error:
VO: [fbdev] 640x480 => 640x480 BGRA
FATAL: cannot initialize video driver.t

However, it playes perfectly with '-vo fbdev2'. Fbdev2 as alternative framebuffer backend. I do not now which frontend uses netsurf, but it may use the non-working one.

Does the sdl backend for mplayer work?

A google suggests that this could be caused by the monitor not supporting the default 800x600 resolution (set in http://source.netsurf-browser.org/libnsfb.git/tree/src/surface/surface.c#n47). Perhaps try changing that to the normal size of the monitor?

Like OP, I seem to be having difficulty initializing the nsfb surface on my raspberry pi 3B+.
See uploaded file for output of nsfb -v -b 16
It's the same whether run from a terminal emulator or tty or use sudo.
