I am a regular supporter of Mozilla. Since changing my desk top computer and re-entering Thunderbird, I have had font size problems, to read incoming E-mails but even more so with sending E-mails, when the print size is almost too small to read. What can I do about his? Please go easy on me : I am a non-techy 91 year old so words of few syllables in everyday terms, please.

have you adjusted the size of the display in Thunderbird?

Did you previously make changes on your old system?
