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.

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:

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?

And those bug didn't updated for year, lets assume they fixed it occasionally.

No new details happened and no reports for TBB3.
