1872516 - Firefox hangs on startup in headless mode when the user is not logged in on the console

Status: VERIFIED DUPLICATE of bug 1866098

(Core :: Widget: Cocoa, defect)

Description

[Lenny Primak]

Attachment: Mozregression screenshot

This is a regression due to https://bugzilla.mozilla.org/show_bug.cgi?id=1845407
On MacOS Sonoma (aarch64) Firefox headless no longer starts at all (hangs) when no one is logged onto the console

To reproduce: ./Firefox_Nightly.app/Contents/MacOS/firefox -headless --screenshot http://example.com
It will hang if no one is logged in on the console (user logs into via ssh)

This affects anyone running automated tests (i.e. Selenium) with Firefox on MacOS nodes.

Seems like we get applicationWillFinishLaunching, but not applicationDidFinishLaunching when running in headless with no user session.

I'm pretty sure you can't do a open with a URL into a headless instance anyway, so I don't think that code path is necessary for headless runs in general, regardless of a user session.

:eeejay we are near the end of the beta cycle. 122.0b9 builds on 2024-01-12.
Though the patch is pending review, any concerns with timing/risk on an uplift for Fx122?

This was also put up for review in bug 1866098, where I have just r+'d the patch. I'll r+ this patch here as well in case we want to uplift this in isolation from bug 1866098.

[Eitan Isaacson [:eeejay]]

yeah, I ended up folding this change into bug 1866098 for simplicity. I'll abandon this patch.
