1873760 - Cannot launch Firefox 121+ with existing profile from command line

Status: RESOLVED DUPLICATE of bug 1873667

(Toolkit :: Startup and Profile System, defect)

Description

[bloink]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/115.0

Steps to reproduce:

On macOS 13.6.3, before updating to Firefox v121+ (from Firefox v120.0.1) I could launch a single instance with an existing profile this way:

/Applications/Firefox.app/Contents/MacOS/firefox-bin -P "$MYPROFILE" -no-remote && >/dev/null

This no longer works.

I can, however, launch Firefox regularly (with the default profile) and then launch an additional instance with another profile via about:profiles and then quit the "default profile" instance.

Actual results:

Firefox should launch with the profile provided as a parameter (by name).

Expected results:

Firefox does not launch at all.
