Status: RESOLVED WONTFIX

(External Software Affecting Firefox :: Other, defect)

Description

[Karlis]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20180206200532

Steps to reproduce:

Firefox 59 64-bit, Windows 10 64-bit, up to date. Tried Refresh and tried removing all addons, even uninstalled AntiVirus software, the problem persists. Unfortunately I had time to test this only on one computer so far.

1. Make sure you have Firefox 59 (bug does not happen in version 58.0.2).
2. Trigger a Save As dialog by "Save Page As...", file download, file upload or other means.
3. If crash does not happen, try right-clicking a folder or file in the Save/Open dialog.



Actual results:

Firefox freezes and hard Windows application crash takes place.

Event Viewer displays following info:
Faulting application name: firefox.exe, version: 59.0.0.6643, time stamp: 0x5aa3576b
Faulting module name: xul.dll, version: 59.0.0.6643, time stamp: 0x5aa35c8c

Expected results:

Should be able to browse and select files and execute their context menus.

I'm unable to reproduce this in latest Nightly, even when clicking randomly on a (large) folder structure, the context menu is working fine and all shortcuts are there, too. 

Could you please get a copy of the latest Nightly and report whether it still happens? You can get it on https://www.mozilla.org/en-US/firefox/channel/desktop/#nightly
Is there a minimized testcase or URL we can use to test?

Today I had an opportunity to try FF 59 64-bit out on my laptop which is a Microsoft Surface 4 machine running Windows 10 (up to date). I was unable to reproduce the bug on that computer.

This must be something connected with Windows Shell Extensions or Windows Shell configuration of my desktop machine. But it is also most certainly something that has changed in version 59.

Currently I do not have an opportunity to test the nightly build, I'll try to do that when I get an opportunity.

I have tested this issue on Windows 10 x64 with the latest Firefox release (59.0.1) and the latest Nightly (61.0a1-20180319220116) and haven't managed to reproduce the issue.

After navigating on a webpage and triggering the "Save Page As..." dialog, the file correctly downloads, no issues occur.
I've also tried opening a file or saving another page as another type and the file is opened/downloaded correctly.

Can you please provide a crash report from "about:crashes", next time you encounter this issue?

Today I had an opportunity to test Firefox Nightly 61.0a1 (2018-03-25) (64-bit), unfortunately it has the same problem.

When viewing about:crashes I do not see any crash data related to the latest crashes. It must be that the crash happens on windows level before report can be produced.

Crash report from Windows Event Viewer:

After disabling my Windows Shell Extensions vendor by vendor using ShellExView utility, I found out that the crash is related to Adobe Creative Cloud shell extensions. 

Disabling following shell extensions makes the bug go away:
AccExt Class (Context Menu)
AccExtIco1 Class (Icon Overlay Handler)
AccExtIco2 Class (Icon Overlay Handler)
AccExtIco3 Class (Icon Overlay Handler)

All of thyese extensions are from file:
C:\Program Files (x86)\Adobe\Adobe Creative Cloud\CoreSyncExtension\CoreSync_x64.dll v1.3.1.405 

Again, these shell extensions have no ill effect on FF 58 or earlier.
