Otherwise you need to go to Spockholm Mafia Tools and will need to get Unframe-MW and Link-A-Nator.. (Unframe-MW is under Stable and Link-A-Nator is Under External Bookmarklets)
They're called "bookmarklets", they're like pre-made bookmarks that you can just drag up to your Bookmark / Links section of your browser!
Finally, Once you have "Unframe-MW" and "Link-A-Nator" accessible to you: load up mafia wars, click Unframe-MW, then go to your "Free Gifts Page" Under "My Mafia" and click "Link-a-Nator".. And follow the on-screen instructions from there.. its pretty simple..
There is an "Add-On" for Mafia Wars that you can install to chrome and firefox, it has a good majority of the features that the bookmark-lets from spockholm tools and code outpost let you accomplish but there is no need to Un-Frame and they are easily accessible and for the most part work better and are more pleasing to use.
