This happened when I was trying to load <http://www.cbc.ca/video/#/Shows/Q_on_bold/Other/ID=1329922589>. Firefox became unresponsive and started beachballing. I attached gdb to firefox and plugin-container and got the following backtraces: (gdb) bt #0 0x903f2066 in __semwait_signal () #1 0x903f1d22 in _pthread_cond_wait () #2 0x903f1875 in pthread_cond_timedwait$UNIX2003 () #3 0x027070f9 in pt_TimedWait () #4 0x02707e4f in PR_WaitCondVar () #5 0x00c88d16 in mozilla::ipc::SyncChannel::WaitForNotify () #6 0x00c865a4 in mozilla::ipc::RPCChannel::Call () #7 0x00c8c6c1 in mozilla::plugins::PPluginModuleParent::CallPPluginInstanceConstructor () #8 0x00c6eff4 in mozilla::plugins::PluginModuleParent::NPP_New () #9 0x00ad2c02 in nsNPAPIPluginInstance::InitializePlugin () #10 0x00adecdf in nsPluginHost::TrySetUpPluginInstance () #11 0x00adefe5 in nsPluginHost::SetUpPluginInstance () #12 0x00ade768 in nsPluginHost::InstantiateEmbeddedPlugin () #13 0x0023e5ca in nsObjectFrame::InstantiatePlugin () #14 0x00245456 in nsObjectFrame::Instantiate () #15 0x003f0213 in nsObjectLoadingContent::Instantiate () #16 0x003f14a5 in nsObjectLoadingContent::EnsureInstantiation () #17 0x005d4163 in nsHTMLPluginObjElementSH::GetPluginInstanceIfSafe () #18 0x005d8e0f in nsHTMLPluginObjElementSH::NewResolve () #19 0x00914488 in XPC_WN_Helper_NewResolve () #20 0x00ed0283 in js_LookupPropertyWithFlags () #21 0x00ed2acf in js_GetPropertyHelper () #22 0x00ea8f96 in js::Interpret () #23 0x00eba044 in js::InvokeCommon<int (*)(JSContext*, JSObject*, unsigned int, js::Value*, js::Value*)> () #24 0x00ebba7f in js::Invoke () #25 0x00ebbecc in js::InternalInvoke () #26 0x00e543b5 in JS_CallFunctionValue () #27 0x009053ba in nsXPCWrappedJSClass::CallMethod () #28 0x008ffe23 in nsXPCWrappedJS::CallMethod () #29 0x00d59ea5 in PrepareAndDispatch () #30 0x00d55f90 in nsXPTCStubBase::Stub3 () #31 0x004526ba in nsEventListenerManager::HandleEventSubType () #32 0x00452ce0 in nsEventListenerManager::HandleEventInternal () #33 0x00470017 in nsEventTargetChainItem::HandleEventTargetChain () #34 0x004709fe in nsEventDispatcher::Dispatch () #35 0x00470bef in nsEventDispatcher::DispatchDOMEvent () #36 0x003b6013 in nsDocument::DispatchEvent () #37 0x0039359a in nsContentUtils::DispatchTrustedEvent () #38 0x003bfee7 in nsDocument::DispatchContentLoadedEvents () #39 0x003c6561 in nsRunnableMethodImpl<void (nsDocument::*)(), true>::Run () #40 0x00d44f4c in nsThread::ProcessNextEvent () #41 0x00d03f87 in NS_ProcessPendingEvents_P () #42 0x00c0a7c2 in nsBaseAppShell::NativeEventCallback () #43 0x00bce378 in nsAppShell::ProcessGeckoEvents () #44 0x95c1f0fb in __CFRunLoopDoSources0 () #45 0x95c1cbbf in __CFRunLoopRun () #46 0x95c1c094 in CFRunLoopRunSpecific () #47 0x95c1bec1 in CFRunLoopRunInMode () #48 0x93ebff9c in RunCurrentEventLoopInMode () #49 0x93ebfc8d in ReceiveNextEventCommon () #50 0x93ebfbd6 in BlockUntilNextEventMatchingListInMode () #51 0x927ada89 in _DPSNextEvent () #52 0x927ad2ca in -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] () #53 0x9276f55b in -[NSApplication run] () #54 0x00bcd9aa in nsAppShell::Run () #55 0x00a485e7 in nsAppStartup::Run () #56 0x0000ed59 in XRE_main () #57 0x00001d48 in main () (gdb) bt #0 0x903ec51c in _longjmp () #1 0x83e58955 in ?? () #2 0x5d8958ec in ?? () As soon as I detached both gdb instances, Firefox started to be responsive again. I couldn't reproduce the problem when I tried to reload that page. This is on a nightly built from http://hg.mozilla.org/mozilla-central/rev/e486018949e2.

Is this a regression, and does it still happen with OOPP off? Otherwise this is just "the plugin is taking a long time to respond to NPP_New".

I only saw this once. I think I waited about 1-2 minutes before I attempted to attach gdb, during which time the entire browser window had became non-responsive. Do we need to block on the plugin from the UI thread like this?
