Bad experience with dark theme

[ttamttam]

When (this is my default setting) I select Thunderbird dark theme: — the Search++ button is not visible (maybe there is a way to have it's color inversed, depending on the theme?) — in the key shortcuts table, every second line is unreadable

Many thanks for your work on this essential addon!

I'd add that under dark mode (Linux) the Prefs window's Rules tab shows white-on-white text for every other (even) row. This can sort of be worked around as the text goes red when the row is selected.

(I think this is a related issue.) When the Nostalgy Preferences are opened the tab labels (Rules, Completion, etc.) are all black on light and readable but when I select another tab the selected tab becomes totally light and the label can't be seen; this continues from that point until the preferences are closed and reopened. It occurs whether the light appearance was set using the Thunderbird light theme or the Mac's light setting (System Preferences/General/Appearance).

This problem still exists, making Nostalgy very hard to use with any dark scheme. See example from my screen with standard dark mode from TB. Should be an easy fix, right? ?

[joreiff]

In case anyone is interested: The following CSS fixes the status bar issue shown by @DrBoym:

hbox.statusbar[insertbefore="unreadMessageCount"] {
    appearance: none !important;
}

image#me-help {
    filter: invert(1);
}

Simply add it to the chrome/userChrome.css file inside your profile folder and restart Thunderbird.

[ttamttam]

Could not. Because there is no chrome directory in my profile folder. And I observe no effect if I create the missing directory and the above file in it.

[joreiff]

The directory does not get created automatically, simply create it yourself. And for newer profiles, you might have to enable this feature in the config editor.

[ttamttam]

Great! Thank you for the instructions!

Thanks for the simple fix @joreiff! I would note that this also fixes the display for anyone using using the DeepDark theme, including (for the most part) making the Nostalgy settings dialogs readable and usable.

[opto]

thanks for that. I have not yet found out how anaddon can find out about dark mode, otherwise Nostalgy could add this.

just did dark mode for expressionsearch-ng, so this will be coming in the next week or so.

I am trying but failing to apply the same workaround for the prefs window's tables in dark mode (above); I've added the following to my userChome.css (in my current profile), and seemingly enabled that in the config editor, but it doesn't work. In the debugger, I don't see evidence of userChrome.css being in the list of possible stylesheets (but don't know if I would). I'm wondering if it's something to do with the prefs. window being a popup (it requires normal debugger access to inspect, not the add-on debugger).

#nrules tr:nth-child(even), #nostalgy_key_rows tr:nth-child(even)
{
  background-color: #404040  !important;
}

If I add that in the debugger as a (temporary) custom rule, it does apply OK. I just can't come up with a way of having it work automatically.

@opto Any news on that topic?

[ptyx-erd]

1. enabling toolkit.legacyUserProfileCustomizations.stylesheets in the Thunderbird config editor
2. Adding /chrome/userChrome.css with the specified code inside (as @joreiff suggested) to the folder C:\Users\ USERNAME \AppData\Roaming\Thunderbird\Profiles\ PROFILE FOLDER NAME \ made this work after restarting thunderbird.

Thx all !

Also that would be great to incorporate this feature in the next version of Nostalgy++ as a majority of people are now using dark mode.
