While I'm in PB mode, does FF3.6 use the data from normal mode cache?

The purpose of asking this Q is: I'm a web developer. I want to visit a site freshly (without any data used from cache). But I don't want to clear all my cache/cookies etc from all the sites I've visited so far. So I wish if I can switch to PB mode and visit this one site which doesn't use any data from normal mode cache .

Firefox doesn't use the disk cache in Private Browsing mode, but does use the memory cache. See the about:cache page.

In Private Browsing cookies from normal mode are not available and a new set of (session) cookies will be created that will be removed if you exit Private Browsing mode.
You can see that in the cookies manager: Tools > Options > Privacy > Cookies: "Show Cookies"
