Problem Description: Firefox for Android does not support immersive system bottom navigation. A fixed black or blank bar remains at the bottom of the screen. The browser toolbar cannot integrate with the system navigation bar, causing fragmented full-screen display.
Drawbacks: The overlapping double navigation bars result in a bloated interface and wasted screen space. The UI is inconsistent with most modern Android apps, bringing a subpar browsing experience.
Suggestion: Please add support for transparent immersive navigation bar. Allow web content to extend fully to the bottom of the screen for seamless full-screen viewing, improving screen utilization and visual experience.
