this is a windows issue causing program fail, have you checked other programs to see if this is doing the same?

hi No other program crash when I unplug my monitors. This is a recent issue, not sure if it is or not since the last update.

Thanks!

PS: to clarify I am on OSX not Windows, so I guess you meant OSX windows.

aww ok yea i'll pass this on to a mac user experienced i'm a linux and windows experienced user thanks for that it does help us to determined how to answer support questions better.

Hi Mastap, Does the Mozilla Crash Reporter come up? If so,

1. Open Thunderbird.
2. Go to Help > Troubleshooting Information. That should open a new tab with info about your Thunderbird setup.
3. Under "Crash Reports for the Last 3 Days" click on your latest crash report. That should take you to a web page starting with "https://crash-stats.mozilla.com/report/index/" and post the address of your latest crash report.

We can then look at the data specific to your crash and have a better idea of what is causing the problem.

perhaps bug 1201401 ?

Hi, I did submit the report through the crash reporte. Does this suffice?

Here is my crash report https://crash-stats.mozilla.com/report/index/0b65c3d2-7068-43c7-8cb7-b8ec00180810

That appear to be bug 1201401 See https://bugzilla.mozilla.org/show_bug.cgi?id=1201401

A summary is that there a currently two suspected causes.

1. A bad HDMI cable connecting the external monitor 2. Different refresh rates on the two monitors. (Perhaps you could offer some information in regard to that).

What I do not see is any sort of workaround.

If other apps were crashing I would suspect my side, yet it is not the case. Only TB crashes.

What would help you help me here? The brand of my cables?

I will check the refresh rates when I plug in at the office tomorrow. Thanks

Moustap,

results?

I can reproduce this at will, with any HDMI cable. I have submitted my crash report here and to Moz. No news. :/

Anyone else experience this?
