I loved the inclusion of Devtools in Firefox, but I always found the font of the Console to be too small,

Looking at Bugzilla, I found a related bug. Inspecting the patch I found that it modified the following CSS rules: .jsterm-input-node and .jsterm-complete-node. So I went ahead and added them to my userChrome.css file: 
.jsterm-input-node, 
.jsterm-complete-node { 
  font-size: 1rem !important; 
  line-height: 150%; 
}
