The Thunderbird Support Forum is the first place to go when you need to ask a question. People will do their best to offer advise and usually can help fix issues. If it is found there is an issue which is reproducable then it's time to post as a bug. Have you accessed the Thunderbird Support Forum and asked about how to control font sizes? If yes, then please post a link so I can pick up the conversation and offer support.

You would need to specifically state all the steps and what font sizes you selected for 'Latin' and 'Other Writing Systems' and provide proof of what you selected eg: images In ' Help > 'More TRoubleshooting Information' Scroll down to 'Important Modified Preferences' section Locate everything that starts with 'font......'

Only changing the general interface size will affect the mail view. Oddly, changing the general interface size from 14px to 15px increases the font size in the mail view by significantly more than 1px, so it seems there's two bugs related to font size in the mail view. Menu icon > Font size > increase or decrease effects Folder Pane, Message List, Menus and Message Pane header and Message Pane. So this is a general increase in various areas and not just specifically the Message Pane contents when reading an email. > Expected results: > > Font sizes set in Fonts & Colors should be used for mail view, like they were in previous versions. It seems that the font size for the mail view is forced to follow the general interface size now, which is not what I want. At this point it is unknown what various font size and pixel size settings you have set up throughout Thunderbird and it's possible they are out of synch. I have come across this on several occasions, but the correct place to sort out Support Issues is in the Support Forum. This forum is for determining whether your issue really is a bug or whether you have created settings that cause a conflict and therefore not producing what you desire. Note: Setting these font sizes will effect the content of an email you open to read whether that be in the Message Pane or in a new tab. Font size is based on pixel size, so I'm assuming you have not altered the preference called 'layout.css.devPixelsPerPx' - it is set up to use the default. I'm also assuming Menu icon > Font size > is not set to be larger than the settings described below. Setting up font sizes for Message Pane - reading of incoming mail - Settings > General - Scroll to 'Language & Appearance' - Click on 'Advanced' You need to set up font size and minimum font size for all the following: Font for : 'Latin' and 'Other Writing Systems' and any other language you may use or receive emails. Setting 'Minimum font size' will override html css in incoming mail. If you set Proportional and Monospace to 15px but do not want any really tiny size fonts, set minimum font size to eg: 12px. **Testing in Windows 10 OS** Thunderbird beta version 117.0b4 Set all my font size to 20px and minimum font size to 12px in both Fonts for: Latin and Other Writing Systems. Second test: set minimum font as 20px **Expected** In the Message Pane: All medium font set as 20px. So it looks rather large. Any font code less than 12px to be displayed as 12px. The font size in Folder Pane and Message List. Menus etc not effected. Second test - all small text will get enlarged and all text looks same size. **Actual** In the Message Pane: All medium font set as 20px. Any font code less than 12px was displayed as 12px. Second test - set minimum as 20px - all text showed the same medium text throughout. The font size in Folder Pane and Message List. Menus etc were not effected. This works perfectly as expected. I cannot reproduce any problem with setting font size specifically for the Message Pane.
