1297821 - Thunderbird 45.x locks up and hogs system resources on MacOS, coincident to getting Unresponsive Script in Firefox

Status: RESOLVED INCOMPLETE

(Thunderbird :: Untriaged, defect)

Description

[John Worley]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:48.0) Gecko/20100101 Firefox/48.0
Build ID: 20160817112116

Steps to reproduce:

You just need to leave Thunderbird running. At some random(?) time, the UI will freeze up, the screen will flicker, and the entire system slows down. The only solution is to quit and restart Thunderbird (Option-Q still works). It may or may not be related to trying to get new mail (I have 4 different accounts).


Actual results:

The UI hangs and the system grinds to a halt


Expected results:

The UI should not and and the system should not grind to a halt

Please start thunderbird in safe mode

Does problem go away?

Starting Thunderbird in safe mode does not make the problem go away. However, I did observe that the hanging behavior seems to appear. oddly enough, when I get an "unresponsive script" message from my Firefox browser and I click on "Stop Script". As far as I can tell, Thunderbird only hangs under these circumstances

Before you do "Stop Script", how much CPU is firefox using? Does the firefox problem go away if you start in safe mode?

And THunderbird is not a problem until AFTER you click "stop script"?

Sounds like a hardware issue.

Feel free to give us more information.
Right now this lacks enough information to say what the problem is, or is not.
