FVWM: two questions about icons

Greetings,

I'm upgrading/replacing a rather old FreeBSD system that I've been
neglecting for some time, and I installed the latest and greatest
fwvm package on this new FreeBSD 12.0-RELEASE system.  All appears
to be working well so far, but there are two small annoyances.

First, the icon used to repreesent minimuzed Firefox windows is
substantially larger than t was for the prior version(s) of fvwm
that I had been accustomed to using.  Since I tend to have a LOT
of different brwosers windoes open and minimized on my screen,
this is likely to cause me some consternation, over the long run.

So, is there an alternative minimized icon available for Firefox?

I should perhaps mention also that I have already installed all
three of teh followuing browsers onto this new FreeBSD system
that I am just now setting up: Firefox, Opera, and Chromium
(aka "chrome").  Somewhat unexpectedly, the minimized icons for
each of these is a different size that the others (!)  That's
right, all three of the icons for these browsers are different
sizes.

That certainly seems a bit odd.

Of all three, the icon used for Opera is the smallest and seems
to be the closest to what I had historically seen, in terms of
icon size, for Firefox.

If this is just as issue with the FreeBSD port/package of fvwm,
then by all means, please do tell me and I'll contact the revevant
FreeBSD port maintainer instead pf whoever is manning this mailing
list.

Just one other thing:  It has long been the case, even with the very
old and very crusty version of fvwm that I'd been using in the past,
that when I minimize a xterm window, I don't get any sort of an icon
in that case.  Rather, those minimized xterm windows end up plopping
themselves over along the right hand edge of my screen, rather than
along the bottom edge (as for the browser icons) and they look like
small "squished" versions of the corresponding original un-minimized
xterm windows.  I'm perfectly OK with the placement of these, along
the right hand edge of my screen, and in fact I prefer that, but I do
wonder if it might not be possible to get those minimized xterm windows
represented as small, standard sized icons also, instead of as smaller
version of themselves.

Any and all advice or help will be appreciated.
