How do I change the display font in Thunderbird

Thunderbird just upgraded to "Supernova". I hate it. I'm trying to adjust as many things as I can to make it look normal, but I'm stuck on the font. How can I change the display font used so that my folders and email information (NOT the font used in email messages themselves) is different from the default?

Also, is there any way to change the density or size of just one pane? My email list is too cramped, but if I try to change the size or the density, it changes the the all the panes, and so then my folder list looks way to spread out.

If you decide to again install version 115, a screen shot will be most helpful.
