I'm trying to remove FireFox native horizontal tab following this link: https://superuser.com/questions/1424478/can-i-hide-native-tabs-at-the-top-of-firefox

However, I couldn't get it to work even thought I use correct path, change config to true for using style sheet, and clear cache

context: path: /Users/PC/Library/Application Support/Firefox/Profiles/xxxxxxxx.default-release/chrome/userChrome.css FireFox version 123.0

Never mind I got it working, when I use Textedit to save in .txt format and change it to .css later when I open it in VS code there a bunch of "\" everywhere. Not sure why, could someone explain how it happen?
