You can use the browser extension Xmarks to open remote tabs from a different remote browser session.
You can download the browser extension here:
http://www.xmarks.com/
After installing the extension in all of your browsers you need to log in with your account. If you're not registered yet, you need to create an account. Use the Option "Open Remote Tabs" to see the tabs you opened in different browser sessions. You can now open either all tabs of a previous session by clicking on a browser icon or just certain tabs by clicking on them.
Note: "Remote Tabs" are only supported in these browsers:
Firefox, Internet Explorer and Chrome
