1981578 - Firefox no longer opens websites, and will not shut down without needing a force quit.

Status: UNCONFIRMED

(Core :: Widget: Cocoa, defect)

Description

[Lili Shi]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36

Steps to reproduce:

Open firefox v141.0.2 on MacOS 15.5, try to navigate to ANY website.

Actual results:

Firefox is stuck in a perpetual loading cycle. Then right clicking the icon and quitting will not work, and eventually right-clicking will prompt a "force quit" option.

Expected results:

Firefox should work. Note that downgrading to 141.0.1 will make everything work again.

Could I ask you to collect a profile of the Firefox process by sending signals from the terminal? See https://profiler.firefox.com/docs/#/./async-posix-signal-control for details. You can upload the collected JSON file on https://profiler.firefox.com/ and then share the link here. Record maybe 20 seconds of you trying to load new pages and interacting with the UI while Firefox is in this state. Thank you!

Sorry, the link doesn't work - you also need to upload the profile using the button + panel in the top right corner. Could you try again?

I don't see a + button in the top right, only the github icon.

I am having the same or similar issue. After a while, I will put my machine to sleep or reboot and then try to open Firefox and opening any page is stuck on loading, except settings, except no changes can be made (the ui shows up tho).

I am able to remedy the situation by removing all the profiles in '~/Library/Application Support/Firefox/Profiles' and restarting Firefox, but then I loose all the my bookmarks and preferences.

User-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:141.0) Gecko/20100101 Firefox/141.0
Version: 141.0.3

Also to note, I don't have any extensions so it is not that.

Thanks for looking into it!
