Please do the following to update Firefox.
- Use Internet Explorer to Download Firefox 4.0.1
- When you see the prompt, choose "Save" and save it to your desktop.
- Then go to Add/Remove Programs, scroll down to "Mozilla Firefox" and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
- Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox
- Finally run the installation file you downloaded to the desktop earlier.
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.
I noticed your Flash installation is out of date which potentially exposes your system to exploits. See http://www.adobe.com/support/security/bulletins/apsb11-12.html
Update it via http://get.adobe.com/flashplayer/
That indicates that you are using an add-on that is not compatible with Firefox 4. For details of how to troubleshoot this to find out what one is causing the problem see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
