New to Thunderbird. Why are the mail box message lines and fonts so small? The only solution to fixing this seems to be to install and add-on. Is this accurate? Is there away to reset in preferences or view. Please note that I am not refering to the font size in writing a message. I want to enlarge the message list and fonts in the mail boxes. It seems strange that this is not a basic function of the program.

Thanks for any recommendations.
