On the "View Image" background

[MrInitialMan]

Is there a way to simply change it to white? Some GIFs that have no background become very hard to see.

You can change the background colour for viewing images from about:config with this setting:
browser.display.standalone_images.background_color
Use the hexadecimal notation to specify colour.

This doesn't work for me. When I view images alone, the background is still the dark gray, despite me changing the setting to #FFFFFF. Anyone have any idea why?

The code below gives images a light grey background. Substitute #FFFFFF in place of #C0C0C0 for white background.

Code: Select all

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document regexp("((.*\\.(png|apng|jpg|jpeg|gif|tiff|bmp))|(^data:image\\/.*))(\\?([^#]*))?(#(.*))?") {

html > body {
  background-color: #C0C0C0 !important;
}

html > body > img:only-child {
  box-shadow: 0px 0px 20px black !important;
}

}

It works for me, and LAR, you do not need that kind of annoying workaround. What Goodydino said is exactly the correct solution.

If you change this value in about:config, you will have to hit "refresh" (F5) on the displayed image to change the background color to what you've set.

Yes, I discovered that it's being overridden by the theme I'm using (PMChrome). When the theme is disabled, the setting works. I've opened a bug report on Github and reported the issue via email to the theme developer.

Until 28.0.0, this setting:
browser.display.standalone_images.background_color;#ffffff
worked as expected. This page is one of my daily visits: http://www.usairnet.com/weather/images/ ... rature.png
Now I only get the default background color.
I don't use any themes or skins, and no other system changes were made.

It is a minor regression due to platform changes. We will get around to forward porting it from Tycho.

Beyond a doubt, this is the most useful and helpful Help section ever. God Bless you all.
