The traditional way to browse a site with multiple sessions is by using multiple browsers at the same time. Are there any Google Chrome / Firefox plugins that can do the same using a single browser?

Not only can you do cross-browser, but you can set up profiles for different computers (Work/Home/Custom) and determine which bookmarks/folders go with each profile. This can help you choose if you want specific bookmarks to be at home, or if you want to leave them at work.
In addition, you can sync Passwords, or Open Tabs on each computer, but only if you want to, of course.
Chrome supports multiple user profiles, you can make use of this to have multiple browsing sessions.
Click on the Chrome Menu (Mac users: Chrome-Preferences) → Click on Add New User. Now, there's a new instance of Chrome with a entirely different profile from the current user, so the cookies and the like are not shared.
Now, when you launch a new window, you can select a user profile to switch between & hence have multiple sessions.

I have created a script for Google Chrome that allows multi-session browsing.
Download the installer, or just run the script directly.
It creates a shortcut that launches a completely separate instance of Chrome which has its own cookies. (In fact, it has its own history as well.) This allows you to test your pages with multiple user accounts at the same time, or use multiple Gmail/Facebook accounts, etc.
