how to change text size in the message list?

Using Thunderbird 24 on Windows 7.

Preferences-Display-Fonts-Size allows me to change the text size in the message pane, but what I want to do is to increase the size of text in the message list above the message pane, and in the Folders list to the left of these.

I need larger text to help an older user with poor eyesight, so any advice will be greatly valued.

I have already set the Windows system font to a workable size.  It doesn't seem to affect the Thunderbird font at all.

Good one Zenos! That's the add-on I need. Very many thanks to you.

While Theme Font & Size Changer 33.1 does increase the font size, it causes the Thunderbird window to fade so much it is basically unreadable on some of my my high res monitors (2560x1600). The only way I found to fix this is to use Help>Restart with Addons Disabled
