Any way to change the color of the active tab in FF57 (CSS?)

Hello,

Love Firefox 57, but would like to change the ACTIVE tab color (currently using the stock "Dark" theme). I know there is a blue bar above the active tab, but I really, REALLY, liked the way the active tab looked in Firefox 56 (solid blue). Any way to change this using CSS or a better way if you have one? I want to keep the "Dark" theme, just change the color of the active tab. It should be able to be done using CSS, but I don't know how.

Any help would be greatly appreciated!

BTW: I need detailed instructions, as I have never done any mods using CSS before. Thanks!

P.S. Right now, I am on the ESR awaiting an extension to be finished porting to a WebEx, but would love to get this info as I have been testing out Firefox 57.

Thanks for your time!

Create a userChrome.css file using these instructions: https://www.userchrome.org/how-create-userchrome-css.html

When you get to the "adding style recipes to userChrome.css" step, use this CSS:

.tab-background[selected="true"] {
background-color: red; /* this sets the color of the tab background */
}
.tab-line[selected="true"] {
background-color : red; /* this sets the color of the line above the tab */
}

You can change the colors listed above to any valid CSS color (you can use this tool: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Colors/Color_picker_tool , copy the "hexa" value, and replace the "red" above with that value).

Hi no.name, when you find something attractive, please share your CSS back.

(For best results pasting CSS here, put <pre> and </pre> after.)

Ok, but everyone has there own taste :) - I'm still trying different combos. I am using the link user1929 gave me in his post to "mix" colors.
