No I don't have it. I thought the line

xrandr --dpi 192 &
or
xrandr --output eDP-1 --mode "3840x2160" --scale "0.75x0.75"

in ~/.xinitrc was sufficient to fix Firefox; it doesn't fix TB.

I just added
Xft.dpi: 192
to ~/.Xresources and not only TB works but LibreOffice works too.
Of course all of this defies the purpose of having an HiDPI laptop but
it is either that or no use at all.

Thank you Andrew.
