Just hit this on 10.7 after a very long uptime: https://crash-stats.mozilla.com/report/index/bp-05184855-bda0-4fbb-bf9f-913d02110705

This seems to happen with Thunderbird too: https://crash-stats.mozilla.com/report/index/bp-3d2e537b-8070-4bb5-a18e-de8582110925

What I see now is different stack than comment 4, and higher crash rate for thunderbird than firefox - at least for the crashes I examined. bp-21034098-5750-4de6-a9ea-5ad422130110 tb 17.0.2 0 libxul.so XPCWrappedNative::FlatJSObjectFinalized nsISupportsUtils.h:149 1 libxul.so WrappedNativeFinalize XPCWrappedNativeJSOps.cpp:617 2 libxul.so js::gc::Arena::finalize<JSObject> jsobjinlines.h:235 3 libxul.so js::gc::FinalizeArenas jsgc.cpp:412 4 libxul.so IncrementalCollectSlice jsgc.cpp:1626 bp-bf842c98-21f0-44b4-b8a9-5d8fc2121223 FF18.0 0 XUL XPCWrappedNative::FlatJSObjectFinalized js/xpconnect/src/XPCWrappedNative.cpp:1336 1 XUL WrappedNativeFinalize js/xpconnect/src/XPCWrappedNativeJSOps.cpp:617 2 XUL js::gc::finalize<JSObject> js/src/jsobjinlines.h:234 3 XUL js::gc::FinalizeArenas js/src/jsgc.cpp:419 4 XUL js::gc::ArenaLists::queueObjectsForSweep js/src/jsgc.cpp:1660 5 XUL IncrementalCollectSlice js/src/jsgc.cpp:3865

I'm not so sure now that current linux and Mac thunderbird crashes are good match to what's happening in firefox firefox 18 bp-c2db1774-71f7-47a4-a01e-a4bcd2130324 0 libxul.so XPCWrappedNative::FlatJSObjectFinalized xpcprivate.h:1615 1 libxul.so WrappedNativeFinalize XPCWrappedNativeJSOps.cpp:617 2 libxul.so js::gc::FinalizeArenas jsobjinlines.h:234 3 libxul.so js::gc::ArenaLists::queueObjectsForSweep jsgc.cpp:1660 4 libxul.so BeginSweepPhase jsgc.cpp:3865 5 libxul.so IncrementalCollectSlice jsgc.cpp:4362 6 libxul.so GCCycle jsgc.cpp:4540 7 libxul.so Collect jsgc.cpp:4655 8 libxul.so js::IncrementalGC jsfriendapi.cpp:172

As a firefox crash, this signature is gone for current versions, so => WFM https://crash-stats.mozilla.com/signature/?product=Firefox&signature=XPCWrappedNative%3A%3AFlatJSObjectFinalized&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_sort=-version&_sort=-date&page=1
