Adaptive Tab Bar Color is a delightful extension that enhances your browsing aesthetics by dynamically changing your browser's tab bar (or theme) color to match the active website.

- Visually Pleasing Integration: Creates a seamless and modern look by subtly blending your browser's interface with the color scheme (often from the favicon or site header) of the website you're visiting.
- Effortless & Automatic: It works right out of the box. Just install it, and the colors adapt automatically as you navigate between tabs – no setup required.
- Lightweight Enhancement: Adds this pleasant visual feature without noticeably impacting your browser's performance.
- Subtle but Effective: Provides a refined visual cue that makes the browsing experience feel more polished and integrated.
- Simple & Focused: Does one thing – color adaptation – and does it elegantly.

That's it! Install it and immediately enjoy a browser that feels more connected to the web content you're viewing. Adaptive Tab Bar Color is a fantastic, simple tweak for anyone who appreciates thoughtful design details. A big thank you to the developer(s) for creating this neat visual enhancement. Highly recommended for adding a touch of elegance to your browsing!
