You can have multiple sessions of Firefox, depending on how you open the links. If you use "tab tearing", you can split each page into its own FF process.

Are you using tabs in a single window or not? I'm guessing not if you have so many sessions.

There is probably more overhead when you create multiple sessions, but it might not be more than if you had them all as tabs in a single session. It depends on the content of each page. If there is a lot of Flash content, then that page would probably consume more resources.
