According to your system specs, you have version 2.0 installed, not Firefox 5.0

Please do the following to upgrade.

1. Go to Download Firefox 5.0.1 and download the installation file to your desktop.
   
   
2. 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).
   
   
3. Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox
   
   
4. 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.

As a precaution, make a backup of your Bookmarks as follows:

1. Hit CTRL+SHIFT+B to open the Bookmarks Manager.
   
   
2. Click the link to Import and Backup and then click Export HTML and save the file somewhere.

Xircal and Safebrowser, thanks so much for your input. I tried Safebrowser's way first since it looked easier, and it did solve the problem. Thanks again.
