thank you for that /very/ useful information.  cannot seem to
reproduce at this time as i'd have to narrow down the dialog box in
which this occurs [i think on a save link in gmail with some
extensions or so is one place] for haelth reasons but i think part of
the problem is that .emacs is not called, and/or that a tiny little
unreadable xterm is launched and emacs is run in it.  why firefox
would do that, idk.

i will quite likely need the information in your post if the .emacs
and/or xterm thing gets solved.  but it turns out that with
/usr/bin/emacs in normal use [no personal script needed] everything is
accessible.  my path doesn't override that.

so idk why ff makes emacs not load .emacs or does an xterm.
/usr/bin/emacs results in indeed emacs25 atm.

gnome and kde are too heavy for my computer, and they can't do
everything fluxbox can, and fluxbox mostly wfm.  i don't get what
things de's do that i need, but perhaps setting default fonts/colors
for various toolkits is one of them.
