Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Thanks for the assistance... about:crashes shows nothing... just a blank screen. I did go into task manager this last crash... Firefox showed "not responding" with zero CPU usage. Farther down... I did find an issue (I will get the exact name when it happens again) .... the Firefox Plugin Container (or something like that) was using like 16% of the CPU... I did an "end task" on it, and suddenly Firefox was responding normally again.

Can you suggest a good way to isolate which plugin is acting up? Also... I did not have this issue in the previous version of Firefox... is it possible to revert to the older version?

Use this link to check that your plugins are up-to-date. If any are listed as unknown or research, do not worry about them.

Separate Issue; Your System Details shows;

Installed Plug-ins

Adobe PDF Plug-In For Firefox and Netscape 10.1.15 Adobe PDF Plug-In For Firefox and Netscape 15.8.20082
Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.

Adobe Reader Version 2015.008.20082 Note: McAfee Security is offered in the download.

Some more information:

DMP files manually generated after the Plugin Container crash are inconclusive... they show a "unknown third party driver" caused the crash.

I did isolate the issue to Adobe Flash (big surprise, right?). Unfortunately I have to leave Flash installed to access several pages that use it. I hope Flash dies one of these days... it is a major PITA! Any suggestions on improving Flash compatibility with the latest version of Firefox would be appreciated!

On the dual Acrobat plugins... I have the latest Reader version installed for Web use.... and an older Acrobat version installed for PDF creation / modification. They do seem to co-exist without issues. I do have the Reader version set to Activate in FF, and the Acrobat version is Never Activate. Seems to work!

I do have some crash reports now... pasted below: Report ID Date Submitted
