Firefox on OSX won't shut down after update

Posted

Whenever Firefox updates on my Mac, Firefox won't shut down, and (as a result) I can't shut down my Mac. A 'Force Quit" doesn't do anything. My only option is to hold the power button down on my Mac for 10 seconds to 'force' a hard shutdown.

After reboot, Firefox works normally (closing Firefox works correctly).

Thanks for forwarding this - I did see it. However, it won't help.

When I update FIrefox, it's usually because Firefox is running and I am prompted to do an update. After the update, Firefox (which was already up) 'hangs' (it didn't shut down completely). I can't restart it without rebooting the machine. Once I reboot, it works fine - so starting it in Safe Mode isn't an option unless I reboot the machine, at which time everything is fine.

Let's try a full reinstall, Download Firefox For All languages And Systems {web link} Save the file. Then;

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.


Look for, and rename any Mozilla or Firefox program folders by adding .old to them.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.

OK - I have downloaded and installed the latest full version of Firefox. Now all I can do is wait until the next update to see if this works.

I'll keep you posted. Thanks.

You may be right - thanks for the post.

It turns out that I can recreate the problem.

I normally run Firefox in Private Browsing mode, but needed to switch to a normal window for one website. Since I couldn't figure out how to start up a non-private window, I reset the preferences (which forced a Firefox restart), and i ended up with 2 instances of Firefox on my dock - my 'normal' one and a 2nd temporary one.

After I was done, Firefox would not shut down. After holding the power button on my MBP to force a shutdown, the restart came up with only one Firefox icon on the dock (as expected), and I was able to proceed.
