Probably a duplicate of bug 1403787.

[:Grisha Kruglov]

Seems like it is. I'm surprised that Bug 1403787 didn't land yet :-( It slipped off the radar.

There seems to be two sets of stacktraces here. One is what Bug 1403787 addresses, and another is this:

java.io.FileNotFoundException: /data/user/0/org.mozilla.firefox/files/fxa.account.json (No such file or directory)

Install age is mostly just around a minute, and uptime is close to "startup"; to me indicates that this is a one-time crash, which makes sense - once that file is created, we won't run into these problems again, and this top crasher will "go away".

As to why this actually happens... a tautological explanation is that we're still racing between pickle file creation and loading the sync prefs activity. We now pickle immediately on account creation, but apparently that's not enough.
