How to set font size on new mail with non-HTML mode

I don't use Thunderbird myself but I have come across a discussion here
http://thunderbirdtweaks.blogspot.co.uk/2012/02/font-sizes.html

Apparently there is an addon to change settings here
https://addons.mozilla.org/en-us/thunderbird/addon/theme-font-size-changer/?src=collection&collection_id=35816d23-50da-46d4-b65f-7180f4c47dec

Note: As you are sending plain text this change is only for your editor. That is the font size seen by people receiving emails from you is not set by you but by their e-mail client.

Hope this helps

The addon is cool, but seems to change all fonts beside of the editor window. Maybe a bug inside Thunderbird core itself?

The blogpost seems only to talk about HTML-mails btw. As its fundamentally wrong to create HTML-mails .... ;)

Hi everyone,

I came across this thread while searching for a solution to a similar issue I'm facing with Thunderbird's plain text email editor. The suggestion to use the "Theme Font & Size Changer" addon seems interesting, but it's unfortunate that it doesn't affect the editor window as desired.

Has anyone found a workaround or a different solution to adjust the font size in the editor window for non-HTML emails? Also, are there any updates on whether this issue has been addressed in recent versions of Thunderbird?

Appreciate any insights or tips you might have!
