At first it was difficult to navigate thru yahoo emails using firefox on my 700m, e.g. no scroll bar. Now I can't read emails at all. I am using firefox 3.5.4. The mail folders, headers, etc shows. But when I click (or double click to make it full screen) on an email, the header is shown (bottom section of screen) but no other text. But if I reply or forward the email, the text and html are clearly shown in the email. Gmail works fine. Is this an issue with yahoo, firefox, 700m screen size? Do other 12in laptops have this problem? What about 13.3in?

Never had any issues with 12.1" notebook in mail or whatever. Try some different resolutions, dpi? If you use FF, i recommend the Default Zoom Level and/or NoSquint extension. Might help.

cheers ...
