## Description

VivaldiFox is a dynamic Firefox theme that brings the aesthetic of the Vivaldi browser to your browsing experience. It features custom theme creation, allowing users to personalize their browser colors just like in Vivaldi. The theme seamlessly integrates with page colors and includes a night mode for comfortable dark browsing.

Designed to work with popular tab management extensions like Tree Style Tab and Tab Center Redux (with "Integrate with current theme" enabled), VivaldiFox enhances Firefox’s interface without sacrificing compatibility. Note that on Firefox versions 59 or lower, a minor text shadow issue may appear but can be resolved by upgrading or applying a simple userChrome.css fix provided by the developer. For issues and further customization, the extension’s source and support are available on GitHub.
