1400619 - Tab crashes when headphones are plugged in or out on videos (Youtube, Facebook)

Status: RESOLVED DUPLICATE of bug 1400465

(Firefox :: General, defect)

Description

[Anthony Miyaguchi [:amiyaguchi]]

When logged into Facebook, plugging in or plugging out headphones will cause the tab to crash. 

I am running on a Mid 2015 Macbook Pro running MacOS 12.10.6 with Firefox Nightly 57.0a1 (2017-09-16). I can reproduce this bug reliably.

I discovered that I couldn't consistently reproduce this issue on Facebook with a known broken version on the Facebook home screen. I noticed that it would only break if there was a video on the page. I then found it would also break Youtube.

My new procedure for reproducing this issue was the following:
1. Plug in headphones
2. Go to youtube
3. Click on the first (top left) video
4. Unplug headphones after page has loaded

It looks like this is related to bug 1399905, and is therefore a duplicate of bug 1400465.
