Working with Microsoft Internet Explorer
Keep the following in mind when using Microsoft Internet Explorer as your Web browser:
QuickTest Professional Web support behaves as a browser extension in Microsoft Internet Explorer. Therefore, you cannot use the Web Add-in on Microsoft Internet Explorer without enabling the Enable third-** browser extensions option. To set the option, in Microsoft Internet Explorer choose Tools > Internet Options > Advanced and select the Enable third-** browser extensions option.
QuickTest Professional does not support tabbed browsing. Therefore, if your version of Microsoft Internet Explorer supports tabbed browsing, you must disable this option in Internet Explorer before using the Web Add-in.
To disable the option in Internet Explorer, choose Tools > Internet Options > General > Change how webpages are displayed in tabs > Settings and clear the Enable Tabbed Browsing option. After clearing this option, you must restart your browser before using the QuickTest Professional Web Add-in.
