userChrome.css and Firefox Developer Edition
Firefox Developer 80.0b7 (64-bit) Mac Catalina V 10.15.5
I've tried using the userChrome.css file to change the background color for the active tab. create chrome folder in profile folder create userChrome.css file and add: .tab-background[selected="true"] {
background-color: #ffffff !important; background-image: none !important;
} Set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE Reboot mac This does not take affect and the userChrome.css file is not visible in Style Editor.
What am I doing wrong? thanks Milton

You can open the userChrome.css file in a Firefox tab to check if the file is a plain text file and not a file with RTF or other formatting code.
Yes it opens in a tab. It is a text file.
