Hey there! Thanks for reaching out. I totally get how adjusting the spacing can make things more comfortable for you. To make the space between "From," "To," and "Subject" smaller in Thunderbird, you can use a little custom CSS magic. Go to "Tools" > "Options" > "Advanced" > "General" > "Config Editor". Search for "layout.css.devPixelsPerPx" and set it to a smaller value, like "1.0" or "0.9", depending on your preference. Just remember that tweaking these settings might need a Thunderbird restart to take effect. Give it a try and see if it suits your taste.

Hello, I did as you wrote.

In "Tools", their is no "Options" listed.

The Thunderbird version I have is the latest: 115.1.0 (64-Bit) Hope this helps you fix my problem.

Thank you for your time. Jean-o

It is tools>settings>general. and that affects ALL text.

And I don't know if it affects spacing.

Hi David, Thanks for the help. It did shrink the text, but it is still not the way it was. I can read the email better by double clicking the email which takes me to just the email. Thank you for your time, Jean-o

Other options are View>Density and View>Fontsize .

Hi David, Thanks for helping. I tried setting the font smaller and it was too hard to read with these 96 year old eyes. Their has to be some way to shrink the From, To and Subject screen. Some one must know.

It's really not a great idea to be tweaking Thunderbird in ways that likely won't work in the future or break your configuration when code is changed.

Suggest patience and wait until a proper solution is made in a public release or a knowledge base article.

Thank you Wayne, I have come to that conclusion and hope it can be changed eventually so that more of my email screen can be used easier.
