+# Profile abstraction for restricting chromium in the lightdm guest session
# Author: Jamie Strandboge <jamie@canonical.com>
# The abstraction provides the additional accesses required to launch
-# chromium-browser from within an lightdm session. Because AppArmor cannot yet
-# merge profiles and because we want to utilize the access rules provided in
-# abstractions/lightdm, this abstraction must be separate from
+# chromium based browsers from within an lightdm session. Because AppArmor
+# cannot yet merge profiles and because we want to utilize the access rules
+# provided in abstractions/lightdm, this abstraction must be separate from
# abstractions/lightdm.
