I use Firefox 3.6. Today it reset itself to default settings; worse it will not retain my customizations. I restored the customizations but after I closed Firefox the next time I opened it, the defaults were back. What's happening? Please help. Thanks.

The only different activities when this happened were that I had just upgraded to Firefox 3.6.12 and shortly after needed to do a 'hard' shutdown. However, the update had downloaded and successfully installed before the shutdown.

Your above posted system details show multiple Java Console extensions.
You can uninstall (remove) the Java Console extensions and disable the Java Quick Starter extension, you do not need them to run Java applets.

See http://kb.mozillazine.org/Java#Multiple_Java_Console_extensions

Disable the Java Quick Starter extension: Tools -> Add-ons -> Extensions
Control Panel -> Java -> Advanced tab -> Miscellaneous -> Java Quick Starter (disable)
