Disabling McAfee SiteAdvisor seems to prevent the crash. But the debug log seems to point to WOW64?

sorry, the log showed that you didn't quit firefox before trying to start firefox from the debugger. this is because our instructions aren't clear/specific enough about the starting conditions (someone needs to improve them). basically: > 0:000> .tlist this is the command we asked you to run > 0n10556 firefox.exe this is the firefox you already had running before you started windbg > 0n7780 windbg.exe this is the windbg you ran > 0n8612 firefox.exe this is the firefox you asked windbg to debug. unfortunately, this second firefox just looked around, saw the first one, asked it to open a window, and then quit. windbg then told you "the thing you asked me to debug quit". please quit firefox, and try following the instructions again. we really will try to improve the debugging instructions and are sorry for the inconvenience (and given that i'm the unfortunate guy who gets to write the apologies daily at this point, believe me, i'm sorry because the typing hurts my hands).

How do I follow the instructions if Firefox isn't running? Use IE?

print it, save it as text and open it in an text editor or use another browser like IE

ok. the log shows firefox quitting (i think, at least based on "last event", but it wasn't because of a previous instance (good!). i'm not sure why it quit... :( can you please try installing the 32bit version of windbg? that'll reduce the number of variables floating around (debugging firefox using a 64bit debugger is still kinda new to me). i'm very sorry about this.

it seems like something is force quitting the process, i guess. after you enter this: 0:000> sxn gp please execute the following: bp kernel32!ExitProcess "~* kp; g" bp kernel32!ExitThread "~* kp; g" bp kernel32!TerminateProcess "~* kp; g" bp kernel32!TerminateThread "~* kp; g" ...before continuing with the normal stuff. instead of 0:000> bp ntdll!LdrpDoDebuggerBreak+0x30 0:000> bp ntdll!LdrpDoDebuggerBreak+0x2c please do: bp ntdll!LdrpDoDebuggerBreak+0x30 "~* kp; g" bp ntdll!LdrpDoDebuggerBreak+0x2c "~* kp; g"

ok, some of my traps didn't work properly, but the key one did: # 20 Id: be0.135c Suspend: 1 Teb: 7ef7c000 Unfrozen ChildEBP RetAddr 082a8dbc 00000000 kernel32!TerminateProcess so, something is forcefully killing us, i think. there's no stack trace here, which is odd. i'm going to have to think about how to track down who's doing this and how. note that typically terminateprocess wouldn't happen and i certainly wouldn't expect to see it on a thread like 20....

The reporter found that disabling the McAfee SiteAdvisor addon makes this "crash" disappear. Could it be that the McAfee SiteAdvisor backend crashes and the addon quits Firefox for security reasons (no longer protected by the addon) ?

The unloaded module nailite.dll would be part of the McAfee product (NAI=Network Associates, Inc.)

Reporter, is this still happening with 3.6.13 or later? Does disabling the Siteadvisor addon still make the crash go away?

Yes to both questions.

Please report to Macaffe then, the siteadvisor is a binary addon and is the issue behind the crash here.

McAfee are working on an updated version of their Site Advisor extension, to prevent the issues it causes with Firefox. To help work out what versions of the extension don't work (for the purposes of blocklisting it in bug 637542), it would be useful to know what version you are using. Please can you go to the page "about:support" (type it without quotes in the address bar) and paste the contents of the extension section as a reply here. Thanks!

thanks for posting the information. I hope we can blocklist this addon from Firefox4

Reopening since now in the McAfee section, so something for them to sort out.

Installed the latest version of Nightly (linked below) and McAfee SiteAdvisor 3.6.0.126: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2013-03-06-03-10-12-mozilla-central/ Attempted to reproduce the crash several times using the test case above, everything worked without any issues. Received the "Server not found" page instead of a crash. Also tried reproducing the crash using another long url without any luck. The website loaded fine.
