Start Faster only works with Windows Vista and Windows 7 for the time being. If you are curious, this is what the add-on does: It installs a service in Windows that allows to speed up the loading time of Firefox’s gorillaesque DLL libraries; this is a service that runs under administrative privileges and permits Firefox to bypass the Windows prefetcher, improving the start-up time of Firefox up 2x faster. One thing to notice is that after you install the Start Faster add-on a shortcut named Faster Firefox will be added to the desktop, which will be the one that you now are going use to start Firefox faster. This idea isn’t new, Mozilla has been trying to implement this optimization for a long time, so you can think of it as preview of what is to come and hopefully in later versions of Firefox we might see this built-in to the core.
