greets!

don't know if it's related to Stretch - I recently upgraded from 
Jessie (now somewhat to my regret) - but I did an update of Firefox 
via the Mozilla online update.

subsequently (and as an effect?) Firefox lost vertical scrollbars. I 
tried various things with the themes (unsystematically) and now have a 
circumstance where I get:

"GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same 
process is not supported"

when I try to start Firefox, Pan and Google-Chrome-Stable. online 
googling has so far yielded nothing useful.

I assume I have some combination of Desktop 'effects' which clash. I'm 
guessing. I can list various things but perhaps I'll wait for wiser 
guidance.

I will say I have:

Redmond as GTK2 Style
Use my TDE Style in GTK3 apps
GTK@ Fonts uses Times New Roman
Decorations: Plastik

(btw I still have the issue of menu items playing hide-and-seek in 
OpenOffice.)
