Firefox doesn't close correctly and stops mac from restarting.

Posted

On Mac OS 10.11.14 El Capitan.

Firefox doesn't shut down when closed.

The dock icon persists, in the force quit window the application is present.

However you cannot force quit - it does nothing.

When you try and reopen the application it states the application is open.

If you attempt to restart your computer at this point it won't let you. And now you have requested a restart you can no longer open any other applications to resolve the issue. This leaves you with one option. A forced shutdown by holding down the power key.

All in all. Pretty bad.

However some bright spark has deduced that you can do the following (provided you hadn't already tried to restart)

Open the terminal window and perform the following commands.

sudo killall launchservicesd sudo killall Dock

Hi Matt

I am not a Mac user, but that obviously should not happen.

Does it help if you give Firefox longer to closedown, at least 10 minutes before trying to kill it or power off. Longer if you clearly see disk activity associated with Firefox after you commence the tying to exit Firefox.

If Firefox has issues trying to close down it should time out, and then start to try to generate and file a crash report. It would be worth looking in about:crashes to see if you have any recent submitted crash reports

If you have problems closingdown Firefox it is normal for the next restart to take longer than usual, sometimes a lot longer. This is because Firefox may need to do additional tasks at start up after a closedown ended unexpectedly.

It would be worth doing a clean reinstall of Firefox. That involves deleting the program files, NOT the profile files.

Just a longshot: Have you set Firefox to forget History when it closes ? If so try a couple of consecutive closedown and restart cycles with Firefox set to the default remember History

Also note use of Trusteer Rapport software may sometimes be connected with this sort of symptom. If so disable or remove such software until it is updated to work with Firefox.

Question owner

What is funny is that I couldn't use Safari to login and comment on the mozilla support site. It doesn't appear to work. Its one thing after another.

Interesting what you mention about Trusteer as that is installed. Its not clearly obvious how to uninstall though.

On a mac there isn't a hard drive light, ideally I would have opened the activity monitor first before trying to quit firefox. Let me be clear I'm not a heavy user of Firefox - its mainly for testing so the browser has very little in terms of extensions and plugins. And i removed the theme too. I could reinstall but it seems unncecessary given the amount of use its had so far.

History is set like most things as default settings so far.

I will monitor it over the coming days to see if the fail to close happens again.

Thanks for the reply though.

Thanks for your report! You're not alone as others have seen this issue too.

It goes without saying this is a really bad issue. Never have I ever seen a program resist being force closed/quit on any OS. Except for those malwares over the years that had that ability. In those cases you had to use the Unlocker program to end task it. But also stopping the OS from shutting down is unheard of to me.

They may ask your for help to debug the issue so they will appreciate it if you can provide anything they may need to investigate this.
