Hi V. Korn,
I know this is a long time ago. You were getting startup crashes with version from 2016/01/26. May I ask you to try that version again and make a http log for me. I am trying to investigate a problem that we have and somehow in that nightly version (because of bug 1242597) it was more often. It was happening to you on the startup and it was reproducible. The http log would help a lot to analyze this problem. 

The old firefox you can get from:
https://archive.mozilla.org/pub/firefox/nightly/2016/01/2016-01-26-03-02-44-mozilla-central/

probably you were using:
https://archive.mozilla.org/pub/firefox/nightly/2016/01/2016-01-26-03-02-44-mozilla-central/firefox-47.0a1.en-US.linux-x86_64.tar.bz2

Thank you very much!

To get http log, please take a look at:

Hello, i tried to reproduce crash with both 2016-01-26  and 2016-01-28 (it was crash happy for me too) with both fresh and my current profile but they both refuse now to crash. I tried almost 10 times with both builds and no result. My suggestion is that several Extension versions have changed since that time and probably that changed something. I'm especially suspicious for NoScript.
If you need i can try to investigate it in this direction, but as is its not reproducing.

Thanks for trying it. I was feeling luck that you are going to reproduce it, but also expected that is not going to work.

You do not need to investigate, it is a lot of work and probably you will not manage to reproduce it.
I will try to reproduce it with NoScript.
Thanks.
