I looked at the Private Browsing Page which was helpful but as to how much information my ISP can collect when I am in private browsing mode, the "Learn More" link was not working. Therefore, I want to know what kind of information my ISP can collect while I am in Private Browsing mode. For instance, are cookies still collected from websites I might visit? My main concern is that I don't want a bunch of spam as a result of a Private Browsing Session.

Private browsing mode stops the details from being saved on your computer. Any data still passes through your ISP so they can still record details of what sites you visit.

Using private browsing mode or not has no impact upon spam.

Cookies are created normally during a private browsing session. The same rules and exceptions are used during a PB session and exceptions that you create during a PB session will last. However all cookies are removed (expire) if you end a PB mode session or exit Firefox. As posted above: it doesn't make any difference for your ISP if you are in PB mode, your ISP doesn't even know if you are. PB mode only prevents data to be stored in the Firefox Profile Folder, all other storage by AV software, firewall, ISP etc. is not affected and will still collect data as usual.
