Hi Jim,

I think the Firefox I am using was built to utilize GTK+-3.x.  If that is correct, I did not see any issues with it despite the fact that the GDK_SCALE environment variable is not set.

I am curious about one thing you mentioned: are actually using TDE (the desktop environment per se) with a window manager other than twin?  If so, I would be interested to know how that worked out for you as I had noted that alternative window managers can be configured.  That might solve at least the "microscopic window resizing arrows" part of the problem.
