firefox : ICE fail after a while

[Robien]

Hey

I am following the progress of webtorrent for a while and I have to thank you for the progress done so far!
I have spotted a bug long time ago but I thought it was a due to the early developpmenet stage of webtorrent and the webrtc implementation in firefox. (I decide to report it before I die ... I am from Paris and... I see dead people... )

The problem is after using webtorrent for a while (on the same page), it can't connect to new peers (log says: "ICE failed, see about:webrtc for more details" in loop)
When I have this issue I can't download anything obviously but I can't browse any regular website in the browser. That part made me think it might be an issue with firefox but as I only spot the problem with webtorrent I thought it might be a good idea to post an issue here first.

How to reproduce the issue:

• open instant.io
• start downloading a torrent (I use wanderers.torrent)
• wait for a while (sorry I don't know exactely how long, but after an hour I have the issue almost all the time, but it might be faster than that)
• firefox can't load any web page and instant.io refuse to start any download.

I am using firefox 44.0a2 developper edition 64 bits for windows for this test but it works with older version too and it's exactly the same thing on linux, the OS I use usualy.
I tried with chrome and it seems to works fine.

This message is repeated for each "ICE failed, see about:webrtc for more details" I suppose.
I am not a web developer so it means nothing for me. If you found anything useful here please tell me :)

Thanks

PS: please notice the "o=mozilla...THIS_IS_SDPARTA" in the log message :)

I'm from Barcelona, Robien. Hold your head up, having fear is what they want for us.

I believe this may be another instance of #551 caused by us opening up too many RTCPeerConnection. Closing in favor of that issue.
