To the reporter:  Can you give us the report link from about:crashes?  What OS are you using?  What camera are you using?

1st Crash is in mozilla::MediaStreamGraphImpl::RunInStableState(bool); I suspect this is a dup.
2nd seems to be something else entirely; are you sure that was from this peer.js issue?

I think this issue is about SSL.
After using SSL, this issue has occured.
Here are another links.(First crash when stream to peer starts, then next crash(firefox restart))

When this machine start to send its camera or application to another peer , firefox crashes.

It always crashed twice??  This is odd...

Please see bug 1191713 - perhaps this is the "Webroot" security software?  That would also explain why SSL is involved.  

from bug 1191713
> overall the correlations for this signature suggest involvement of Webroot security software (but apparently not the one particular crashes by the reporter)

How do I use this to reproduce the crash?

Also: there's a bug in the (unmaintained) peer.js's handling of onnegotiationneeded, which is fixed in the skyway fork (right nils?)  This may fix the errors I see when I hit "Arama Yap" in the example:

JavaScript error: https://video.polarcomputer.com/peer.js, line 2410: TypeError: pc is undefined

(That's in MakeOffer(), invoked from pc.onnegotiationneeded, which we may be firing earlier than peer.js anticipated.)

How do I use the link (https://video.polarcomputer.com/webRT.html) to reproduce the failure?

What versions of Firefox have you tested with this?

Yes. NTT's peerjs clone https://github.com/nttcom/peerjs has this problem fixed.

And yes this copy of peer.js https://video.polarcomputer.com/peer.js suffers from the problem fixed here https://github.com/nttcom/peerjs/commit/4a238a6234785772f9dcbb01bbde1cd07ae6fa8d
Note: applying the fix in that commit fixes it for Firefox >= 40, but leaves Firefox < 40 dead in the water.

I have resolved this issue.
I didnt check Peer.js last version because couldnt find anywhere until now. All download link was broked. Now can be downloaded and may resolve some other bugs, i will test.

Peer.js functions in ajax.done , crashes firefox.
