Change default color of Firefox when opening links in a new tab

alirezanoori replied

I'm using Stylish addon for Firefox with a default dark css. I also have changed the default Window colors in Windows registry. This has changed the about:blank page's color to a dark one. But when I open a link on a new tab, before the page loads, Firefox is showing a blank page with white background. I wonder how can I change this white color to a different one.

Try to style the about:newtab page with this selector.


@-moz-document url(about:newtab){
#newtab-scrollbox { background-image: none !important; background-color: #ffc !important; }
}

Sorry to say, but it didn't help. My new tab page already has a dark background. What I what is to change the "White" color when I "Ctrl+Click" on a link or select to open it in new tab and immediately switch to it before it loads. When I add a new tab, it has a dark background.

One way you can do that if you are using a third party theme is to add this line into the browser.css file in the browser subdirectory in the .jar file.

browser {background: blue;}

Change the colour to whatever you like, then put the revised browser.css file back into the archive and reinstall the theme.

I created a folder named "Chrome" in this location: C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[profile]\

and created an empty userChrome.css file with this line:

browser { background-color: #373739 !important; }

It worked fine. Thanks for the replies.
