Fill Screen

Browser automatically resizes to fill the remaining screen space.

How It Works

When the sidebar opens, your browser shrinks to fit the remaining space. When closed, the browser expands back to fill the screen.

Setup

Open Preferences → General
Set Browser Integration to Smart Attach
Enable Fill Entire Screen
Grant Accessibility permissions when prompted

When Sidebar Hides

By default, browser windows expand to fill the full screen when the sidebar hides. You can change this behavior in Preferences → General → When Sidebar Hides. See Sidebar Panel - Behavior for all options.

When to Use
