I've also opened FB9861639 with Apple for this issue.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Do any of the suggestions in this article help? https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding

I have just upgraded my machine to macOS 12.3 beta as well and I'm unable to reproduce.

I don't think that link is relevant. Firefox hangs on launch, and cannot be used at all. CPU usage isn't high, and it seems from the process sample like it is stalled with a pthread_cond_wait deadlock.

Starting Firefox with -safe-mode launch argument reproduces the issue.

If you want me to run a debug build, I am willing to.

I see this in the log:

This seems related to amfi_get_out_of_my_way=1 bootarg. I have another issue that has not been looked at by Mozilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1722827

Seeing as only Firefox suffers from these issues with amfi_get_out_of_my_way=1 on Monterey, I'd say Firefox has become very hostile to my environment.

i am also using amfi_get_out_of_my_way=1 and firefox hangs on launch. after some time i can click something, however every interaction causes another hang (with spinning beachball for > 10sek). websites don't open at all. i am on macOS Ventura 13.3.1

Interestingly, LibreWolf is working without issue. I was trying it out since i need Firefox on my mac. it is in sync with the lastest firefox version - so whatever is causing the problem is related to what LibreWolf is removing: https://librewolf.net

Comment 9

[Leo Natan]

For me, adding the following boot arg fixed the issue:

ipc_control_port_options=0

Comment 10

[chriswep]

thanks! that works. that should narrow down the issue significantly for whoever is fixing this

Comment 11

[Leo Natan]

I don’t think anyone is fixing it. Mozilla set it to such low priority, nobody is going to look at it, unfortunately. Gone are the days of “hacking”. Now it’s just “unsupported security”.

Comment 12

[chriswep]

you are probably right. at least there is a solution more discoverable now - so this issue still serves some purpose
