Well, I found the solution. It sure didn't take very long.

Type in 'about:config' (without quotes) into the location bar.
Type 'itms' into the filter bar.
Find the preference named 'network.protocol-handler.external.itms'. Under the value column it should say false.
Double click on the entry to change its value to true.
The next time you click on a link, for example U2's Album Page (, Firefox should warn you similarly to the image robot_guy attached in his previous post. Hit Launch Application and you should be in good shape.
