Minimal Mode: Automatically hide the top of the browser on hover

[Luis-Cerna]

I would love Firefox to include an option that automatically hides the entire top part of the browser — including the tab bar, address bar, and buttons — and only shows it again when the mouse hovers over the upper edge of the window.

This would allow users to enjoy a clean, distraction-free experience, similar to fullscreen mode but without hiding the operating system’s taskbar or requiring F11.

The idea is simple:

• When the user activates “Minimal Mode,” the top UI area hides automatically.

• When moving the mouse to the top edge, the bars reappear smoothly.

• When the mouse leaves, they auto-hide again.

This would be especially useful for laptops and small screens, giving more space to web content while keeping the browser controls accessible when needed.

Thank you for considering this idea — Firefox already offers great customization, and this feature would take minimalism and usability to the next level.

That can be done with the autohide CSS found here.
