Make sure that you allow the plugin-container process in the firewall.
See http://kb.mozillazine.org/Plugin-container_and_out-of-process_plugins

There are other things that need attention:

Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

• Java Plug-in 1.6.0 for Netscape Navigator (DLL Helper)

Update the Java plugin to the latest version.

Thank you for responding. My java plugin was up to date and so was all my plugins, but alowing the plugin through my firewall helped alot. It has only crashed one time so far. I will come back when i have used it a while, to see if this was the permanent fix i needed.

Thanks you

The fix was not permanent. Have anyone got any other suggestion? or know what is wrong?
