Could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement? (More info: Diagnose Firefox issues using Troubleshoot Mode)

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most recent 7 - 10 crash reports, and copy them. Press the Reply button. Now go to the reply box and paste them in.

I'm sorry but neither of these responses are something I haven't done. The last crash report available is from several months ago, this problem is not registering with mozilla apparently. All drivers are replaced and updated to be sure. Safe mode is ineffective.

Does that mean you do not get the Mozilla crash reporter but instead the Windows crash dialog?

I have to defer to others in interpreting Windows event log data.

I suppose so, I don't get the prompt from mozilla to submit the report or anything, a window pops up that simply says, Mozilla Firefox has stopped working, searching for a solution etc. I'll have a look at the windows logs, damned if I know what they say either.

That is a system error message, not from Firefox.

This is not a cure, but should let the web page load without crashing.
