MacOS: If not already running, Firefox does not load requested URL on launch MacOS 26.5.2, Firefox 152.0.4

How to reproduce: 1) Set Firefox as the default browser 2) Completely quit Firefox 3) Open a URL (e.g. open Spotlight, type a query, select "Search the web", or any of the many other ways) 4) Observe Firefox opens but does not open a tab with the externally requested URL

This used to work fine. It still works on Windows. Reproduced on two different Macs. If Firefox is already running, it works as expected.
