Note on the screenshots

This style is compatible with any theme, the one that I'm using the Dark Space theme.

CSS Customizations Included

The provided CSS code makes several modifications to streamline the Firefox UI:

• Hides the navigation bar by default, showing it only when the navigator-toolbox is hovered over or focused.
• Adjusts tab appearance for minimalism.
• Hides various UI elements like the tab close button and title bar buttons for a cleaner look.
• Extension menu shown in cleaner way.
• Optionally you can set the font to "Cascadia Code" across the UI for consistency and readability (If you have it installed).

Conclusion

MinimalFox aims to offer a cleaner, more focused browsing experience by minimizing UI distractions. Remember, custom user styles like this are subject to break with future Firefox updates, so adjustments may be necessary over time.
