Mozilla Accuses Microsoft of Using Dark Patterns to Push Copilot on Windows

Overview

• Mozilla said Microsoft forced its Copilot AI onto Windows 11 by auto‑installing the Microsoft 365 Copilot app without consent and by adding a Copilot keyboard key that is hard to remap.
• Microsoft has already announced a pullback, saying in March 2026 it would cut Copilot entry points in built‑in apps like Snipping Tool, Photos, Widgets and Notepad after what Mozilla called a user backlash.
• Mozilla described a broader pattern that steers people to Microsoft products, citing the Windows taskbar search that always opens Edge and Outlook and Teams opening links in Edge even when another default browser is set.
• Firefox pointed to its own approach as an alternative, noting an AI Controls panel in version 148 with a one‑click “Block AI Enhancements” switch that remembers the user’s choice across updates.
• The complaint adds to competitive pressure, with Opera filing an antitrust case in February over distribution tactics that it says make it harder for rival browsers to compete on Windows.
