FindItem ranks #2 for Mac crashes (#26 overall) for Thunderbird 52.1.0. These crashes only happen with Sierra. And for all pratical purposes not before 52.0.1. 45.x crash rate is near zero. (one of the earliest is bp-e9bb55f5-b819-4d15-925b-cb03c0170427) Also, no corresponding signature in 45.x, based on correlating users whose crashes have email addresses.

Are there any steps to reproduce? I don't get my TB 52.1.0/1 on Sierra to crash.

(In reply to Nomis101 from comment #1) > Are there any steps to reproduce? I don't get my TB 52.1.0/1 on Sierra to crash. Not so far - one of the disadvantages of not being a high volume crash. Earliest crashes I find are 53.0b2 like bp-cd56b655-3f94-4e2d-80d4-eecd40170505. No nightly crashes. No crashes reported for 53.0b1 or 52.0b*. Comments indicate this happens when getting new mail or opening mail. I am attempting to determine whether all reports are pop accounts.

All crashes are via [NSTextView dealloc] or [ChildView dealloc]. Then, this crashes when [NSTextInputContext dealloc] releases internal objects. bp-a75adcd8-c0b4-47e7-956d-ba78b0170515 is Firefox issue. So moving to Core - Widget: Cocoa.

These crashes do not happen that often: yesterday I had TB open and in use for all, day and the first crash of that day happened in the evening, here is the report: https://crash-stats.mozilla.com/report/index/746f55eb-8545-4806-93c5-c32b90170517 I think I had just sent an email when it happened, it was like "send an email, switch to another workspace to do something and notice that TB had crashed". I try to pay attention more next time it crashes. I am using no POP accounts: I have several IMAP accounts configured (143/STARTTLS). I am using 52.1.1 for Mac. If you would like me to try out some other version, please let me know where I can download it.

#24 crash for 52.1.1

(In reply to Nomis101 from comment #1) > Are there any steps to reproduce? I don't get my TB 52.1.0/1 on Sierra to crash. User comments vary. But the most common comment is "deleting message". Next most common is "reading email". Example of the former is bp-e8dd2da5-0d53-4d71-9960-e83e40170623 from a user who has crashed 66 times in one month. What do you think we need to resolve this?

This seems to occurs that any window (child view) is closed / disappears. And 100% (except to bp-e6f5ac9b-7e62-4620-849b-28fe20170627. It is another issue) is on macOS 10.12. I think that this may be OS bug, but I don't know why this crash occur.

Sadly, I don't know. Could this happen only on 10.12, because we are building with an older SDK?

Crashes dropped to near zero for beta 55 and 56. So something happened between 54 and 55. - https://crash-stats.mozilla.com/signature/?product=Thunderbird&release_channel=beta&_sort=-date&signature=FindItem&date=%3E%3D2017-02-28T21%3A36%3A25.000Z&date=%3C2017-08-28T21%3A36%3A25.000Z#graphs - https://crash-stats.mozilla.com/signature/?product=Thunderbird&release_channel=beta&signature=FindItem&date=%3E%3D2017-05-28T21%3A40%3A33.000Z&date=%3C2017-08-28T21%3A40%3A33.000Z#graphs So the question is - what got fixed? (assuming mac users are not somehow stuck on 54 beta) 10.12.6 16G29 is the latest sierra build from late July, and afaict it had no impact on 52.3.0 where crashing is still going strong https://crash-stats.mozilla.com/search/?signature=~FindItem&product=Thunderbird&date=%3E%3D2017-08-21T21%3A59%3A26.000Z&date=%3C2017-08-28T21%3A59%3A26.000Z&_sort=-date&_facets=signature&_facets=version&_facets=platform_version&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=platform_pretty_version#facet-platform_version https://crash-stats.mozilla.com/search/?signature=~FindItem&platform_version=%3D10.12.6%2016G29&product=Thunderbird&date=%3E%3D2017-08-21T21%3A59%3A26.000Z&date=%3C2017-08-28T21%3A59%3A26.000Z&_sort=-date&_facets=signature&_facets=version&_facets=platform_version&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=platform_pretty_version#facet-version

I would expect it was any Core change. But which of those, I don't know. Is the any change log of what was changed between 54 and beta 55?

Noteworthy, crash-stats has zero crashes for High Sierra, and overall 9% of Mac crashes are High Sierra which is a significant percentage and no doubt growing. So crash seems specific to 10.12, and crash is gone in 10.13. Still, a very high crash rate for Macs overall, ranks #14 for TB52.4.0

#1 Mac crash, And still in 57.0b1 bp-312c77ac-30e5-4694-990c-4bf6f0171110 OS X 10.12 (garrideb) " Read msg in vertically-expanded mode, reduced to normal size, clicked on get msgs, crash." I did more snooping around and find no 10.13.x crashes of comparble crash volume - other than shutdown crash.

Is bp-066f15a8-9985-43ef-a066-cb7570171007 @ libsystem_kernel.dylib@0x1bfce with nsChildView::DoRemoteComposition on the stack related?

This crash id is GPU related, so it isn't same issue.

No crashes for Thunderbird users on 10.13. So should we close this?

About 40% reduction in crashes since mid-January

(In reply to Wayne Mery (:wsmwk) from comment #17) > No crashes for Thunderbird users on 10.13. So should we close this? I guess so? Realistically we're probably not going to spend time on it.
