Oops! Sorry Cor-El... But I applied the change you recommended, and it seemed as though it was going to work, but it didn't. I even re-started the 'puter to see if that would enable the correction. I also remembered to hit "apply" when the opportunity came up.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

• Don't make any changes on the Safe mode start window.

In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.
Try to disable hardware acceleration.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Restarted in Safe Mode and selected "standard" options... Worked fine. Now just need to add the second address window for google searches... Have the Mozilla window all across the page, and like having the separate smaller Google window.

OK, Got It! Restored the default tool bars. I promise never to mess with these settings again!
