Every time you click a link, Windows 11 quietly launches a second copy of your browser just to pass it along, and Firefox is now testing Microsoft’s fix
AI-summarised brief · reviewed before publication
Mozilla is testing a change that lets Windows 11 hand links and Start‑menu launches directly to an already‑running Firefox window, eliminating the extra firefox.exe process that currently starts a new instance. Early tests show the handoff takes about 3 ms versus 70 ms, a speed boost similar to Microsoft’s “accelerated warm launches” feature that Edge already uses. The patch is controlled by a hidden flag and requires Microsoft’s limited‑access API, which Firefox can access via its existing taskbar pinning code. The feature remains in development and is not yet available to users.
💡 Why It Matters
- · Faster link handling reduces startup latency, improving everyday productivity for Firefox users on Windows 11.
