Theme Changes Some Components to Dark-mode Despite Override

Hiya,

I use a theme which some years ago (after a change in the way Firefox handles dark-mode preferences) changed all UI and websites to use dark-mode. I was able to keep using the theme, and mostly override this behavior by setting:

`layout.css.prefers-color-scheme.content-override = 1`

However, this didn't take for some components, such as the sidebar and bookmark editor window, which still continue to use dark-mode.

Is there any way to completely disable dark-mode everywhere, and still use my preferred theme?

Cheers, Afraz

You can edit the theme manifest file and change "color_scheme" to "light" then either submit it as a new theme or install it on Developer Edition with signature enforcement disabled.

We can rule out `userChrome.css`, because I don't have one :)

It could well be an "incompatible" theme. I got it from the normal theme page for Firefox, and this started happening some time ago, when Firefox changed the way themes effect dark-mode.

I'd really like to keep using this theme though, so am willing to create the necessary entries in a `userChrome.css`. Trouble is, I have no idea what I need to set. Is there documentation somewhere I can look up for changing the appearance of all the extra UI windows like the history browser, bookmarks browser, etc.?

Marked @zeroknight's answer as correct, but it bears further explanation.

This is what needs to be added in the manifest:

``` ...

   "properties": {
     "color_scheme": "light"
   }

... ```

It seems that if a theme doesn't set `properites.color_scheme`, then Firefox defaults to "dark" (my OS is set to light), which is disappointing.

Themes are meant to override the OS theme. The light/dark color scheme is decided by the theme's toolbar and text colors if one isn't specified.

So given the following manifest, Firefox would use "dark"?

{

 "theme": {
   "images": {
     "theme_frame": "fox1_head.png"
   },
   "colors": {
     "frame": "#12455e",
     "tab_background_text": "#ffffff"
   },
 },
 "version": "2.0",
 "name": "Have a Light Fox Dream",
 "manifest_version": 2,
 "description": "Enjoy more!"

}

"tab_background_text": "#ffffff"

Light text will make the color scheme dark.
