TorBrowser crashes in nss3.dll

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.
