[Bug 1857167] [NEW] Firefox freezes due to a broken pipe when debugging

[Seija Kijin]

Public bug reported:

When I attempted to create a new tab and load Twitter (two Twitter tabs
are running with feeds streamed to the device), the entire app froze due
to a broken pipe.

I was debugging Firefox at this time in order to find a memory leak.

Steps to Reproduce:
1. Launch Firefox
2. Open a Twitter tab
3. Open a Google Docs tab
4. Open another Twitter tab

Expected Results:
Both tabs load Twitter information without issue or freezing

Actual Results:
Firefox becomes unresponsive entirely.
