I do not have any problems connecting to Internet. The problem i have is not a problem with firewall settings. It's a problem with FF crashing.

Did you read the part on crashes?

Crash Reason EXCEPTION_ACCESS_VIOLATION_READ

nvwgf2umx_cfg.dll = NVIDIA D3D10 drivers = NVIDIA Corporation

See if there are updates for your graphics drivers https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration

Make sure all programs are up to date.

Version of graphics drivers installed is the latest version available. Besides, all other software (games, for example, that use graphics resources more than anything) work perfect.

I called for more help.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

How to disable Hardware Acceleration {web link}

Hardware acceleration is disabled. In Safe Mode situation is the same. Report ID: bp-31d8bcfe-49b8-4cc0-814d-f6c840210203

bp-31d8bcfe-49b8-4cc0-814d-f6c840210203

The report is the same as the above reports.

No, it is not the same. In reports above nvwgf2umx_cfg.dll is marked red. In this last report there is no nvwgf2umx_cfg.dll in Modules section.
