1) FF 15.0.0.4619 on Windows PC 64 bit machine. No themes; about a dozen fairly standard plug-ins; a few extensions - fairly vanilla setup. Been having occassional problem this past week in viewing web PDFs.

Crash occurred after some program (adobe ??) wanted to do routine update.

2) Upon clicking FF icon pop up indicates "problem and unexpected crash" but clicking details button does NOT provide any info. Clicking on Restart FF button offers me option to Start in Safe Mode or Quit FF.

3) Starts in Safe Mode and first time I did that FF reported Java as being disabled and NOT upto date. Did Java update/install (Java Platform SE 7 U7 10.7.2). FF still will not start except in Safe Mode.

4) Re-booted computer ... Clicking FF icon brings up pop up with problem and crash sentence but no details. Following screen offers Reset to Default option, and upon clicking Reset it takes me back to the same pop up - so I am stuck in a loop that seems to accomplish nothing. Using Reset upon entering Sage Mode results in same loop.

I really hate using IE so appreciate any assistance in getting back to beloved FF.
