A java window appears for a couple of seconds and then Mozilla crashes. My AV Nod32 blocks the main file (see summary) but it can install and execute an .exe file in the C:\Documents and Settings\%CurrentUser%\Local Settings\Temp dir.

I got Mozilla Firefox 3.5.9.

Reproducible: Always

Steps to Reproduce:
1. Open the web site:

Actual Results:  
Loading the main page, when the flash starts a small Java orange window appears and then Firefox crashes.
What version of Java do you have installed? What does say about whether it is up to date? Are your other pluigns such as Flash up to date as well?
Attached file Plugin Check (obsolete) —
My Java version is 6.0.200
sorry, but it is too much of a risk to open a pdf just to get the plugin version numbers.

You need to update Quicktime and Flash. The plugin check report is incorrect in stating that your Flash is up to date.
Attached file Plugin check updated
I can trust to navigate this site with no fear?..
Not yet. Still investigating.

You also need to get rid of Adobe Acrobat. you don't appear to be using the latest version ("9.3.2": they finally added the version string to the description so people can tell), but even that version is currently being exploited in the wild with no patch available yet (maybe in another week there will be an update).

If you can't live w/out Acrobat and can't use another PDF reader for a week then follow Adobe's advisory and delete the authplay.dll
Reporter, any updates with latest plugins and Firefox version?
