Hello, I use Thunderbird with the system default theme (dark on win 11). It is great, and when reading Emails, the background is white. So no mails get messed up. But when replying to mails, the background of the textarea is black and some mails do have black text. So it is impossible to write a mail and keep calm.

Is it in the config or somewhere else possible, to change the color of the textarea to always white / bright?

I do not need any information on how to change the theme for everything to bright as this is not an option.

Thank you!

I'm using the Windows dark theme for Windows and Programs In Thunderbird I'm using it's 'dark' theme.

However, I can choose to use a composing white or dark background via this option. Try this:

  • Settings > Composition
  • Under 'HTML Style'
  • Do you have this selected: 'Use readers default colours' ?
  • If I select this then the composing background is dark.
  • Uncheck that option if it's selected.
  • Set Text colour as black and background as white.
  • Open a new write message.

This suggestion may not work with system dark theme, but it works with Thunderbird dark theme: I'm referring to the addon called Dark Reader. It works for plain text and HTML.
