Internet Explorer 8 is the latest browser from Microsoft. IE8 comes with a very useful feature that help its users to determine which add-ons are slowing down IE page load and IE.
In Internet Explorer’s manage Add-on dialog there is a column called “Load Time”. This column show average time taken by each Add-on when you open a new tab or a new window.
To open the dialog, click Tools –> Manage Add-ons. You can sort the add-ons by load time by ungrouping them (right-click the column headers, then choose Group By –> None) and then clicking the Load time header
