1423648 - Firefox unable to spawn subprocess on startup results in Immediate Crash

Status: UNCONFIRMED

(Toolkit :: Startup and Profile System, defect)

Description

[chezsmithy]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.70 Safari/537.36

Steps to reproduce:

This has been reproduced on OSX Sierra 10.12.6.
Using firefox Nightly, Beta and 57.0.1 Release build.
In all cases an immediate crash occurs.
When launched from the command line, I can get firefox to start, but the console is filled with messages related to failure to spawn subprocesses.

I removed profiles, and deleted and downloaded new builds.
I removed Mozilla and Firefox directories from Library / Application support.
I cleared Caches.
I validated my workstation has latest Sierra patches.

This started on December 4th after a restart. 
Latest software install is Xcode 9.2 on that date.
I do have the Safari Technology Preview Installed.


Actual results:

When launched from the command line I see the following:

trg518999:Application Support r999999$ /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin -p

Expected results:

Firefox should launch normally.
Seems like disabling E10 does help with this.
