Something like this question has been asked so many times, searching for other's answers has become useless. The answers vary over the years and Thunderbird version numbers, not to mention that I can't even find documentation from Mozilla on this topic (official method of changing font size for average user; official list of css keywords, their format, and examples of use; etc.).

I am trying to increase the size of the Thunderbird fonts—not the ones used to display an email, but the ones used to show my list of accounts, mailboxes, and folders and the list of emails I have received (Table View, not Card View). For what its worth, I've already changed the font magnification to 1.5x.

I set toolkit.legacyUserProfileCustomizations.stylesheets to true, and created a chrome folder in my profile directory. In it I put this userChrome.css:

/* Set font size in folder pane */ treechildren::-moz-tree-cell-text { font-size: 18pt !important; }

/* Set font size in message list page */ treechildren::-moz-tree-cell-text { font-size: 22pt !important; }

However, restarting Thunderbird (multiple times with various font sizes) shows no changes. What do I do to change my font sizes? (The average user shouldn't even need to know about profiles or style sheets!)

There are options in the View menu for controlling these things. You may have to undo what you have done to make them work.

Thanks. View -> Font Size -> Increase Font Size worked. I didn't have to undo my previous efforts (which had no effect). Note that this also affects the size of message contents.

You should be able to control text in message bodies in general settings. You will have to change settings for Latin and for other writing systems (or whatever that option is called).
