@worldwidewerner @Vivaldi This is the standard Chromium behaviour. If the address field was at the top, it would not seem that dramatic. But I understand your frustration.
But I would recommend that you switch from the bottom navigation (back, home, app switcher) to the more natural gesture control, then you only have a small line at the bottom (see screenshot). Espescially with android 15, if the app has enabled the edge-to-edge feature. More and more apps have this now.
