On Mojave, Firefox will often stop responding after I come back and unlock my Mac. How can I fix this?

Geplaatst

This one is hard to pin down, but occasionally Firefox will go unresponsive but will accept one previous mouse action (like clicking a tab) when I put Firefox in the background by clicking another open non-Firefox window and bringing it to the front.

How this happens:

1. I lock my macbook and step away from the desk for an undetermined amount of time. 2. I come back to my desk and unlock my computer. 3. I click on firefox to browse for something and it doesn't respond 4. I'll click another tab that isn't in focus, nothing will happen 5. I click on any other open application and I will notice that Firefox will change to the tab I had just clicked on 6. If I go back to Firefox, it will not respond to anything until I bring some other application to focus.

Sometimes, if I wait a long time like 10 or 15 minutes, the problem will resolve itself. Usually I just get frustrated and close Firefox.

I feel like this has to be a problem between Firefox and some other application that I run. Some other appications that are typically open are:

iTerm2 Spotify Lastpass Plugin Microsoft Outlook Atom.io Sometimes TweetDeck Maybe another Firefox profile

I have been unable to regularly reproduce this issue, but it will typically happen multiple times a day.

One other behavior that I have noticed is that I can click the address bar and nothing visible happens, but if I start typing, the suggestion bar will pop up and accept the text I am typing. I am including a picture of that behavior

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hi:

I started Firefox in safe mode and the problem still exhibited itself.

I think this is a bug, is there a way to enable some debug logging?

Thanks.

I did not want you to work. Just use the computer and see if the problem is still there.

This is, unfortunately, still a recurring issue for me. I can not make the problem happen and I don't have time to sit in Safe Mode and try to make it happen. Are there other debugging steps I could try? Is there a flag I can pass to Firefox at startup that might reveal some debugging information I could utilize?

I'm currently on Mojave 10.14.1

Thank you for your help.

I called for more help. You should also post your question on a Mac support forum.
