Nightly 2015.11.25?
OS X 10.10.5 (14F1021)
E10S: Off
Reproducible: Unknown – happened only once

I was using a few tabs (I have hundreds of others open, mostly unloaded) and then suddenly no more HTTP (and apparently wss) connections would work from Nightly anymore. I didn't think to check ftp at the time. The think the two tabs I was using most recently were https://www.facebook.com and https://www.namecheap.com/. I sampled the process with Activity Monitor and will attach it next.

Other debugging notes:
* invisionapp.com was outputting errors: "Firefox can't establish a connection to the server at wss://ws.pusherapp.com/…"
* about:networking wouldn't populate the table body on any of the four tabs and there were no errors in the Browser Console once this happened.
* CPU usage was ~200%
* Toggling Wi-Fi and Nightly's Work Offline didn't remedy the issue.
* I could ping www.google.com and 8.8.8.8 fine
* Safari worked fine to load a test site

Perhaps there was a deadlock somewhere in Necko?
