FF 59 hanging up entire system - OSX - anyone else?

[bluloo]

Since upgrading to FF 59 yesterday, my system has been periodically unresponsive for 10-20 seconds at a time. The first few times, I almost rebooted as it appeared the entire system hung - but I pretty much live in FF, so it's always been running.

Happens waking from sleep as well. System takes 20-30 seconds to respond to any input, before bringing up the login window.

Edit - looks like the wake from sleep thing persists even with FF closed.

Quitting FF, and using Safari eliminates the problem.

Anyone else experiencing similar behavior, or have a fix?

Have you tried starting the program in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode

Running FF 59.0.1 on OS 10.13.3 with no problems. Note just because you have a FF window open does not indicate it is a FF issue. On the other hand running Safari for a while with no issue also does not point that way.

I would do as DanRaisch suggested and try FF in safe mode; I have noticed some quirky extensions. Also you might try a temporary test profile, your profile may be corrupted.

To create a new temporary profile. Quit FF and then go to

Applications > Utilities and launch Terminal.app

Then paste this in exactly without the quotes

"/Applications/Firefox.app/Contents/MacOS/firefox -P"

and hit return

You will see a screen that looks like this



click on the "Create Profile" button and follow the instructions. See if that helps.

To go back to your old or default profile simply quit and restart FF from the profile manager and select your default profile.
