Workaround for Business Link
If you have rackets instead of properties, go to Tools> Greasemonkey> Manage User Scripts. Select Mafia Wars Exp Remaining and uncheck the Enabled box. Refresh your Mafia Wars Page and drag a business link from either Moscow or Cuba up to your Firefox Quick Link bar. Then go back and enable Mafia Wars Exp Remaining in Greasemonkey. Refresh the page again and use the Business Link you just created to get to your businesses. It doesn't matter which city you get the link from. When you click on it in Moscow, it goes to Moscow Businesses and from Cuba, it goes to Cuban Businesses.
