Help & Support

This may be caused by the Google toolbar's AutoFill feature. You can turn this feature off. First open the toolbar options page (click the "G" icon in the search bar and select "Manage..." from the drop-down list).

For older versions, click the More tab, and then under "Extras", untick the "Automatically highlight fields that AutoFill can fill" option. Newer versions just require that you untick the Autofill box on the Browsing tab, and still newer versions have the AutoFill option on the Features tab.
