firefox uses 100% CPU when browsing

When browsing at the main page of, firefox uses 100% of my CPU capacity. I have the flashblock addon installed, which allows me to control whether embedded flash applications are run or not, so it is not due to flash. Does anyone have an idea what it is on this page that is causing the problem?

I went to the site and enabled most of the scripts. I didn't have a problem with the site using Firefox 3.0.10.
You might try the noscript plugin. Also kill the npviewer.bin process if is hung. You could also start firefox with the profile manager, or in the safe mode:
Mozilla options
        -height <value>         Set height of startup window to <value>.
        -h or -help             Print this message.
        -width <value>          Set width of startup window to <value>.
        -v or -version          Print Firefox version.
        -P <profile>            Start with <profile>.
        -ProfileManager         Start with ProfileManager.
        -no-remote              Open new instance, not a new window in running instance.
        -UILocale <locale>              Start with <locale> resources as UI Locale.
        -safe-mode              Disables extensions and themes for this session.
  -jsconsole           Open the Error console.
If you create a new profile and run firefox using the new profile, that might give some clues whether the problem might be with firefox or a script in your original profiles environment.

Good Luck!
