(demo :https://webrtc.github.io/samples/src/content/peerconnection/constraints/) ， so we refresh firefox in setttings. then we restart firefox , we find that the firefox crash in xul.dll always and can not access any website even about:crashes page. Actual results: 1.firefox crashes everytime restart. We first find the issue in firefox 51.0.1 64bit . that's our tester' report before: Windows 7 64bit professional + Firefox 50.1 64bit - OK Windows 7 64bit professional + Firefox 49 64bit - OK Windows 7 64bit professional + Firefox 51.0.1 32bit - OK Windows 7 64bit professional + Firefox 51.0.1 64bit - Crash if refresh firefox Windows 7 64bit Ultimate + Firefox 51.0.1 64bit - OK Windows 10 64bit + Firefox 51.0.1 64bit - OK Now we find the issue also exists in Firefox 55.0.3 64 bit. Windows 7 64bit professional + Firefox 55.0.3 32bit - OK Windows 7 64bit professional + Firefox 55.0.3 64bit - Crash if refresh firefox Expected results: everything should be normal.

Can you provide the crash id?

(In reply to Alex Chronopoulos [:achronop] from comment #1) > Can you provide the crash id? we find that the firefox crash in xul.dll always in windows's crash report(not the firefox crash report). and can not access any website even about:crashes page. there is no crash dump created. we reinstalled a 32bit version of firefox 55.0.3 now, there is no crash dump in about:crashes page. you can reproduce the issue in Windows 7 64bit professional + Firefox 55.0.3 64bit. or you could tell us to how to collect useful information for you.

weren't there some issues with Refresh in 55? Perhaps this is related; or it could be a separate bug entirely. This sounds like Refresh is causing a perma-crash on startup, which is bad. Can you loop in someone involved in Refresh?

Matt, can you take a look here since you worked on bug 1388611? Or, help us find someone to investigate for beta 56? Thanks! Andrei, can your team help try to reproduce this in 56?

Too late for 55.

Are you saying you do get a Windows crash report? If so, please include a stack or more information about where/how it's crashing. You are refreshing by clicking the button from about:support?

Since this seems to be 64-bit-specific, I'm thinking you may be hitting some recent issues we've seen. Would any of the following third-party software be installed on affected computers? * Bug 1268470 - crash in klsihk64.dll (Kaspersky security DLL) * Bug 1347867 - crash in CrashReporter::OOPInit (Quick Heal antivirus DLL) * Bug 1369361 - Startup crash in abort | _acrt_RtlGenRandom (Lenovo OneKey Theater)

I can't reproduce this on my machine running the same OS version and Fx version. We really need to get more info about the crash and since the reporter knows the crash is in xul.dll there is likely more information about the memory address or stack which would be super helpful. cpeterson, any idea who could help here if the reporter provides more info?

my os's language is chinese, the os 's crash information is below: 问题签名: 问题事件名称: APPCRASH 应用程序名: firefox.exe 应用程序版本: 55.0.3.6445 应用程序时间戳: 599ed8ae 故障模块名称: xul.dll 故障模块版本: 55.0.3.6445 故障模块时间戳: 599edd23 异常代码: 80000003 异常偏移: 0000000000dc8407 OS 版本: 6.1.7601.2.1.0.256.48 区域设置 ID: 2052 其他信息 1: 216c 其他信息 2: 216c21f4f0b9e7875522b19a4053d62a 其他信息 3: 46b3 其他信息 4: 46b310b792c3147eda8707b67c041053 the crash dump I have captured manually . but the file is too large to upload. I can not find the pdp file the release(55.0.3.6445) belongs to. what should I do next?

@ dmajor, do you have any suggestions for how to get more information from a xul.dll startup crash that triggers the Windows crash reporter instead of the Firefox crash reporter? @ xpeng, can you please share your about:support "Copy text to clipboard" information from 64-bit Firefox before you "Refresh Firefox"? Do you have any third-party anti-virus or security software installed, such as Kaspersky or Quick Heal? Are you running Windows in a virtual machine or on real hardware? You said that you could not see the WebRTC video in Firefox 55.0.3 64-bit on Windows 7 Professional 64-bit before you refresh Firefox. I wonder if there is a connection between the video not working and Firefox crashing after "refresh". Does the video demo work with Firefox 55 32-bit or a 64-bit version of Firefox before Firefox 55.0.3?

It will have information about your computer that would be the same for 32-bit and 64-bit Firefox.

Thanks. Unfortunately, I don't see any obvious clues explaining why the video would fail or why 64-bit Firefox would crash after a profile refresh. Someone with more Windows debugging experience will need to take a look..

Sounds close enough to me.
