-Integrity is a new security concept introduced in Windows Vista. Securable objects within the system, including applications and their associated windows, directories and files, and registry keys have an integrity level associated with them. The general rule of integrity is defined as "no write-up", implying applications with a lower integrity level do not have security rights that allow access to objects with a higher level. In addition, objects running at a low integrity level often have "no read-up" rules applied which restrict access completely. Restrictions are independent of user level security restrictions.

 Firefox 2.0 currently runs at the default "medium" integrity level. The goal is to add support for running at both low and medium integrity without adversly effecting the browser's usability or user experience.
