The list of messages at the top of the Thunderbird window (From / Subject / etc.) uses a font that is very small and hard to read. The issue is: How can the user increase the size of the font so that it is readable?

The platform is a Mac computer running OS X 10.9.5 with Thunderbird version 31.3.0.

OK, that solution worked fine. I now have complete control of the fonts, colors, and other Thunderbird features. Thank you very much.
