Ultimate Scrollbar Customizer is a robust accessibility tool designed to solve the problem of modern "invisible" or low-contrast scrollbars. Whether you need high-visibility neon colors, a transparent "ghost" outline that doesn't cover text, or just a wider grab handle, this script gives you complete control via a modern visual interface.
It is built to be CSP-Safe (Content Security Policy), meaning it works on strict websites like GitHub, Google, and Banking apps where other scripts fail.

🌟 Key Features

  • Visual GUI Editor: No coding required. Open a settings panel on any site to tweak width, colors, and outline thickness with a live preview.
  • Smart Presets: Instantly switch between 5 professionally tuned styles:
    • Outline: A transparent "ghost" bar with a neon border (perfect for preserving screen real estate).
    • Neon: High-contrast yellow on black.
    • Classic: A standard, usable gray Windows-style bar.
    • BnW / WnB: Strict Black-on-White or White-on-Black modes.
  • Panic Mode: Stuck on a site where you literally can't see the bar? Right-click the Tampermonkey menu and hit "⚡ Force: Black on White" to instantly fix the page without opening the UI.
  • Per-Site Memory: Your settings are saved individually for each domain. You can have a subtle gray bar on Wikipedia and a bright green one on Spotify.
  • Deep CSS Targeting: Uses advanced selectors (*::-webkit-scrollbar) to force scrollbars to appear even inside complex web apps (like Chat interfaces and Gmail) that try to hide them.
  • Native Eye Dropper: Includes an 8-bit color palette for quick selection, plus a button to launch your OS native color picker.
