Increase the body preview font size in Thunderbird.
In thunderbird, when i click an email and look the panel below. The font size is so small, i tried going through option and display and changed everything. Still did not change the font size.
Is there way to change the body font side panel to be bigger.?

hold Ctrl and scroll your mouse wheel?
IS there a way to make it automatic size when opening the panel? Instead of keep using the scroll wheel.
There is, but it requires Thunderbird to disregard the fonts specified by the sender.
On the toolbar 
> Options > Display.
Set the default font and size, note that the size is in pixels so will be about 30% smaller that it's points equivalent.
Click advanced, again set the fonts and sizes then deselect the option to allow messages to use other fonts.
