Browser Like Ghostzilla (But Different Proxy Per Tabbed Browsing)

I Love Ghostzilla and the way it works. I need the browser to work exactly like ghostzilla does. GhostZilla is Open Source so it shouldn't be hard for an experienced programmer to play with the codes. What I basically need is for the Tabbed Browsing to Be able to use a different proxy server for each tab. Basically it will be used to create "chatter" on forums, etc. Main Concept would be to be able to log into the same website, from 1 browser but each tab should be able to log into a different account via proxy server. I do not want to have 2 browsers open for this... Thank you! ## Deliverables Browser needs to act exactly like GhostZilla, the only difference would be the tabbed browsing proxy option. Thank you!
