12// NOTE: Keep these in order since we need test all those paths according
13// to priority. For example. One machine has multiple users. One non-admin
14// user installs Firefox 2, which causes there is a Firefox2 entry under HKCU.
15// One admin user installs Firefox 3, which causes there is a Firefox 3 entry
16// under HKLM. So when the non-admin user log in, we should deal with Firefox 2
17// related data instead of Firefox 3.
