From my memory, I think they use a LRU algorithm to purge files from the pf cache; this still doesn't explain why Firefox wasn't in my pf cache - I tested with just firefox open on my desktop after a fresh reboot. Regardless, is there a way for us to figure out how Chrome loads in a jiffy and employ some of their techniques in Firefox?

Obviously adds some time to your boot, but it does work quite well. It just keeps firefox.exe in memory. I'd say it's fairly close to Chrome if you use it (still not as fast, though). Works with 3.5, 3.6, and 3.7 from what I've tested. For those of you that don’t want to wait for the startup time to improve, you could just use Firefox Preloader.

Perhaps you (and I) have things like antivirus programs which push other apps out of the cache? (There's a ceiling on how many apps are cached) Manoj: The superfetch file for Firefox is currently in /windows/prefetch, but I didn’t do anything to change it.

For some reason Superfetch doesn't seem to be caching it, even though it's constantly in use. I'll poke around and see if there are things that can prevent apps from being monitored and cached by Superfetch.

I was poking around and couldn't find a prefetch or super-prefetch file for Firefox on my Vista machine (maybe I didn't look hard enough). Cold start performance of Firefox would be improved substantially if Windows could figure out the order of page loads for Firefox.exe; the reason why applications *feel* snappier on Windows 7 is because of super-fetch and dll load dependency removal.
