The No Add-ons mode allows Internet Explorer to temporarily run without any add-ons like Toolbars, ActiveX controls, etc. The No add-ons mode in Internet Explorer is rather useful when you want to troubleshoot incompatible browser add-ons or extensions. It is also very useful when you want to troubleshoot a problem like say freezing of your IE, to identify whether it is related to any add-on.
Add-ons are programs that supplement your web browser with additional features such as tool bars and ActiveX controls. Some come pre-installed in Internet Explorer while some are installed via the Internet. It is relatively easy to install Internet Explorer add-ons. They require your permission before getting installed on your system. But some may do without your consent.
