## Description

<b>🌈 Match the theme-color of the website with Firefox's UI</b>

This is how Safari 15 and toolbars on mobile browsers behave.

Highly inspired by <a href="https://addons.mozilla.org/en-US/firefox/addon/adaptive-tab-bar-colour/" rel="nofollow">Adaptive Tab Bar Colour</a>. Part of the code has been taken from it. The main differences:

<ul><li>A cleaner codebase with less features</li><li>Colors in URL bars, active tabs, text color, etc are handled differently. Better contrast and readability.</li><li>Reacts only to theme-color values from the website. It doesn't have the dynamic color algorithm that tries to match the website's header or background color that Adaptive Tab Bar Colour has.</li><li>No settings per website. No toggles. Just install and forget</li></ul>
Compatible with <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3898cac9f9fd2d2702f9668f877d1e6066acd4864d5d806cf311f15502a17be1/https%3A//darkreader.org/" rel="nofollow">Dark Reader</a> 🤗
