I am using XP home edition. This comes up in a Javascript application window every time a new window opens in FF. I do not get this error in IE. I can open other tabs in FF and they are fine, just not other windows. Thank you very much for any help!

Do you have that problem when running in the Firefox SafeMode? http://support.mozilla.com/en-US/kb/Safe+Mode Don't select anything right now, just use "Continue in SafeMode."

If not, see this: http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+theme...

Thank you very much!! You were right on with your advice. It was an add-on so I just uninstalled it and the error went away. Thanks again!
