Description
This policy setting prevents Internet Explorer from displaying a notification when the average time it takes to load all the user's enabled add-ons exceeds the threshold. The notification informs the user that add-ons are slowing their browsing and displays a button which opens the Disable Add-ons dialog box. The Disable Add-ons dialog box displays the load time for each group of add-ons enabled in the browser. It allows the user to disable add-ons and configure the threshold. If you enable this policy setting, users will not be notified when the average time it takes to load all the user's enabled add-ons exceeds the threshold.
