Calendar event screen: Description textbox backgroud color

[soistheman]

I don't know when this started, but when I open calendar event screen for new/edit evnets, at the bottom of the screen there is description tab with textbox. The textbox's background color is controlled by Window's default app color settings. This leads to the problem I am having which is on Window's color settings, I am using dark mode. On the other hand, on Thunderbird, I am using Light theme. With this combination, the textbox's font color is black and background color is dark grey which makes reading text on Description textbox very very very hard. However other tabs like Attachments or Attendees, their textbox's background color is white, so these textboxes don't have the same problem.

My settings:
Windows 10 Home 10.0.19042 Build 19042
Thunderbird 32-bit 91.3.2

Does the same thing happen if you launch the program in Mozilla Troubleshooting mode?

The following style may help.

Code: Select all

/* Thunderbird userContent.css */

@-moz-document url-prefix("about:blank") {
  body { background-color: white !important; }
}

Remember to set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true, then restart.

I would think safe mode would change the Thunderbird theme back to using the Thunderbird System theme, so it wouldn't help.

Adding CSS will probably break the bug fix when applied.

That may be applied in 91.4.0 when released soon.

I just tested...

The troubleshooting mode doesn't reset the dark theme to the system theme for me.
