Changing the Default Font in Thunderbird

Thanks to Sandy Ball and Nikki Massaro Kauffman for this handy tip!

Thunderbird uses a default font size of “8” to display the messages in your Inbox. You can easily increase the size of the font to create a larger display of the same messages. So if your eyes could use a break from small print, give this tip a try!

Changing the Font Size

  1. Open any of these programs NotePad, WordPad or DreamWeaver; then make a new file containing the text shown in red below. Then choose “Save as” and name your file userChrome.css.
  2. Next, go to C:\Documents and Settings[yourusername]\Application Data\Thunderbird\Profiles.
  3. Open the .default folder.
  4. In the .default folder, create a new folder called chrome.
  5. Double click to open the chrome folder.
  6. Copy or move your newly created userChrome.css file into the chrome folder.
  7. Finally, open Thunderbird. Your messages will display in the revised font size.

Handy Hint

If the font size is too large or too small, you can use NotePad or WordPad to easily change the font size. Note that the file shown here contains "font-size: 10pt" ... you can simply increase or decrease the number as needed.
