Thunderbird默认字体及字号修改方法咨询

Hey there! I totally get how frustrating it is to adjust font size and style separately for every email and your signature—let me break down the steps to set a permanent default in Thunderbird:

• First, open Thunderbird and click on the Tools menu at the top (on Mac, this will be the Thunderbird menu instead). Select Settings (some older versions might label this as Options).
• In the Settings window, switch to the Composition tab (this is where all email writing-related settings live).
• Under the General sub-tab of Composition, scroll down to the Fonts section. Here you can pick your preferred default font, adjust the size, and even set a default font color. Hit OK once you’ve got it set how you want.
• For your signature: If it’s plain text, the default font settings you just applied will automatically take effect. If you’re using an HTML-formatted signature, open your signature editor, select all the signature content, use the formatting toolbar to set your desired font and size, then save the template. From now on, your signature will use this fixed format without needing manual tweaks each time.

Quick extra tip: If you also want to adjust the default font for reading emails, head to Settings -> Display -> Fonts & Colors to tweak those preferences too.
