I want to change background color of Thunderbird start page from white to medium gray, hard on my eyes now

more options

Hello, I have bad eyesight. I would like to be able to change the background color of my Thunderbird start page message pane windows from stark white to whatever hex color I desire. Such as medium gray which causes much less eye strain. If its in the code how would I access that? And I believe this would be an optional feature that many people with eye problems would truly appreciate. Thanks for any help with this.

What do you mean by "start page"? What we would normally refer to as a start page shows only until you start reading messages, so it's not clear why it would give you trouble.

I suspect that you are talking about the message list. The easiest thing to do would be to apply a theme, assuming one can be found that provides a suitable colour scheme. Otherwise you could create a userChrome.css file where you can override the usual colours. A related file, userContent.css, can be used to override the colours in messages themselves.

Yes thank you Zenos, You are correct I was referring to the message list and messages themselves.

I will attempt to create a userChrome.css file and go from there.

As a related question, are the available Thunderbird themes editable by me or are they locked up by their creators?

Thank you for your help.

I have just looked at a theme to check. You download an .xpi file which is effectively a zipped archive. You can open that (change its extension to .zip if that helps) and edit the contents, rename to .xpi then apply (i.e. install) it.

The one I have just looked at (Nautopolis) is chock full of css files. Your problem may be to identify which are relevant to your needs.
