1. Navigate to `%APPDATA%\Mozilla\Firefox\Profiles` (you can copy/paste this) or locate the exact directory by visiting `about:profiles`.
2. Create a folder named `chrome` then create a file named userChrome.css inside it and paste this code.
3. If userChrome.css doesn’t seem to work, open `about:config` and set `toolkit.legacyUserProfileCustomizations.stylesheets=true`.
