Description

TorBrowser with Firefox 17.0.5 crashes out of the blue when I have many tabs open. Super frustrating, because I can't restore the session and lost all my research.

Faulting application name: tbb-firefox.exe, version: 17.0.5.4839, time stamp: 0x5159dcb1
Faulting module name: nss3.dll, version: 3.14.3.0, time stamp: 0x5159cb1f
Exception code: 0xc0000005
Fault offset: 0x00032be6
Faulting process id: 0x2f80
Faulting application start time: 0x01ce444ff6f243ba
Faulting application path: C:\Tor Browser\FirefoxPortable\App\Firefox\tbb-firefox.exe
Faulting module path: C:\Tor Browser\FirefoxPortable\App\Firefox\nss3.dll
Report Id: 82e43196-b48c-11e2-a8c6-1c659dad87fe

PS: I tried to set Version and Component, but there's no TorBrowser or Firefox.

Interesting. Can you somehow reproduce that or give some steps which one could try?

mikeperry: I hope this is a patch issue (although I fear an issue with the build setup is more likely...).

Code from offset of nss3.dll:

mov     eax, [esi+54h]

That from nssCertificate_Destroy:

NSS_IMPLEMENT PRStatus
nssCertificate_Destroy (
  NSSCertificate *c
)
{
    nssCertificateStoreTrace lockTrace = {NULL, NULL, PR_FALSE, PR_FALSE};
    nssCertificateStoreTrace unlockTrace = {NULL, NULL, PR_FALSE, PR_FALSE};

    if (c) {
	PRUint32 i;
	nssDecodedCert *dc = c->decoding;  <---- Crash here

c points to nowhere, and it's not NULL it seems.
Any known fixed bugs that would to fix that too or it's something new? Would it be triggered by some firefox patches?

Can you provide a stack trace?

Or a repro case?

It seems like https://bugzilla.mozilla.org/show_bug.cgi?id=700499
And those bug didn't updated for year, lets assume they fixed it occasionally.

No new details happened and no reports for TBB3.
Closing.
