Set-up custom font, font size, and color for writing new and reply e-mails in Thunderbird

Question

I know that I can select the font, size, and color for writing each new and reply e-mails in Thunderbird, but I don't want to have to do this each time. I want to set-up the default font, size, and color for all new and reply e-mails. It already comes up with a default one, but I want to change it, but can't figure out how to do this. I'm sure it is quite simple, but I don't know how to do this. Thank you in advance for help.

Answer 1

Tools > Options > Display > Formatting tab
Default font: select font
Select size : eg; 14
Click on 'Advanced' button and set all the sizes to 14
Select : 'allow messages to use other fonts'
click on OK
Click on 'Composition'
Under the 'General' tab
Suggest you set HTML font to 'Variable width' and Size : 'Medium'
Select the 'Text colour' you would like to compose email using
Select the 'Background colour' you would like to use when composing emails.
click on OK to save all changes.
This will set the display email list to the selected font.
It will allow received emails to use the font the sender used.
When you compose an email it will also use the same font settings.
The message 'Display' settings in the above section also apply to messages that you compose. The settings are not sent, so they do not affect how your messages appear to recipients.
The settings in the ''Composition' section can affect how messages are sent. If you make unusual choices, then people who receive messages from you might find them difficult or impossible to read. Hence, why I suggest you leave it as 'Variable width' and allow the 'Display' settings to set the default used for composing emails.
