Running Firefox 28.0. Just updated, that did not help. The font size on Firefox and Thunderbird increased for the headers, tabs, toolbars, drop down menus, etc. What is in the display appears normal and can be adjusted using the ctrl +- keys. That has no effect on the toolbars, headers, etc. My resolution is at max, icons small, text size at 100%.

You can set the layout.css.devPixelsPerPx pref on the about:config page to 1.0 or on Windows 8 to 1.25 and if necessary adjust layout.css.devPixelsPerPx starting from 1.0 in 0.1 or 0.05 steps (1.1 or 0.9) to make icons show correctly.

Use an extension to adjust the text size in the user interface and the page zoom in the browser window.

You can look at this extension to adjust the font size for the user interface.

You can look at the Default FullZoom Level or NoScript extension if web pages need to be adjusted after changing layout.css.devPixelsPerPx.

I managed to make it better, but it only changed Firefox not Thunderbird. Things are still screwy, but better.
