1868859 - [macOS Intel] Firefox does not open links sent to it when Firefox is not running

Status: RESOLVED DUPLICATE of bug 1818194

(Core :: Widget: Cocoa, defect)

Description

[Will B]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:120.0) Gecko/20100101 Firefox/120.0

Steps to reproduce:

Another app or macOS will try to open a page in Firefox when Firefox is not running.

"Open previous tabs and windows" is enabled. Firefox is my default browser. Three pages are pinned while there are five open tabs.

Actual results:

Firefox will launch but the page requested by another app or macOS does not display, only the tabs saved from last session.

This has been an issue with Firefox for at least the last two years on macOS Intel.

Expected results:

Firefox should display the page sent to it by another app or by macOS even if Firefox is not running.

A more specific example:

• Close Firefox
• Run Geekbench 6 CPU or GPU benchmarks
• When benchmarking is complete, Geekbench will attempt to display the results by launching Firefox
• Firefox launches but does not show page requested by Geekbench, only saved tabs from previous session
