Is the problem still there?

Non of the crash reports were from today and it was today that the restart occurred... Its happened in the past randomly, but I cannot remember if a crash occurred and the browser automatically starting on the same day.

The top handful are from today

Product Firefox Release Channel aurora Version 50.0a2 Build ID 20160911004011 OS OS X 10.12 OS Version 10.12.0 16A319

Signature: IPCError-browser | ShutDownKill

Attention Sumo's there are 30 related bug reports

I've called for more help.

When you started in Safe Mode, did you have any problems?

The ones you mention are from today, are the ones I opened today which did not have a BP value.... they were not found on Support site... when I clicked on them again, they were on the Support site... so they 'transmitted' today but were from past crashes. I verified that by looking at the date on them in Safe mode before clicking on them.

As for the browser, I never said I had a problem running the report. My question is "Why does the browser start/stop on its own at random times in the day? it shows a blank page, and then within 30 seconds the browser closes again". Is this a sync function? I've never had any browsers which opened on their own and closed to maintain they status. Thats what background processes do.

Are you using ad-blocking add-ons? That could be an ad opening, and the blocker closing it.

FF was NEVER open. It started on its own, stayed open for 30 seconds and then closed. FF was never running. Thats the point.

My original posted started.... "With FF not running..."
