Additional info:

Q. How do you know that Firefox is running in reduced privilege?

A: Well, Start SaferFirefox thru the start Menu. Try saving this webpage in C:\ or C:\Program Files or C:\Windows or C:\Windows\System32

If you get a warning message, asking you to save to My Documents instead, then Firefox is running in reduced privilege. (which also means spyware can't infect your critical system directory)

Note: It will also block registry writing to HKLM if any (but not HKCU).

However, if you are installing Firefox extensions, then don't run in Reduced privilege.

(Note: DropMyRights does not works on Vista)

Thanks.

This is only necessary if you are logged into your machine as an administrator, right?

[Geej]

Yes, this is only necessary if you are logged into your machine as an administrator (which generally what majority of home user do)
