Hello,
believe or not i'm avast's employee. I will ask forum moderators to add me to avast group.
The reason why you see avasts dll marked as red is because during crash mozzila takes a dump of the browser process and displays all threads with stacks and unknown libraries are marked with red color !
That is why you see aswjsflt and snx - but they didnt cause the crash. The crash occured it thread 0 with stack :
js::XDRAtom<1>(js::XDRState<1> *,JS::MutableHandle<JSAtom *>)
js::XDRScript<1>(js::XDRState<1> *,JS::Handle<js::Scope *>,JS::Handle<js::ScriptSourceObject *>,JS::Handle<JSFunction *>,JS::MutableHandle<JSScript *>)
js::XDRInterpretedFunction<1>(js::XDRState<1> *,JS::Handle<js::Scope *>,JS::Handle<js::ScriptSourceObject *>,JS::MutableHandle<JSFunction *>)
js::XDRScript<1>(js::XDRState<1> *,JS::Handle<js::Scope *>,JS::Handle<js::ScriptSourceObject *>,JS::Handle<JSFunction *>,JS::MutableHandle<JSScript *>)
js::XDRState<1>::codeScript(JS::MutableHandle<JSScript *>)
js::MultiScriptsDecodeTask::parse(JSContext *)
js::HelperThread::handleParseWorkload(js::AutoLockHelperThreadState &)
js::detail::ThreadTrampoline<void (&)(void *),js::HelperThread *>::Start(void *)
To confirm it please send us dumps and try to rename aswjsflt.dll for a while - it might help.
There is avast ftp server where you can upload dump files for analysis. (
ftp://ftp.avast.com/incoming ) Zip all your data into aswJsFlt_keeps_crashing_firefox_12_02_2018.zip and upload them.
Thank you
