I have been seeing the same problem since I upgraded to 8.04. I can see that the preferred application was set to 'Custom'. I don't know why that would be as this is a fresh install using my old gutsy /home partition. Now I've set it to 'Ubuntu Sensible Browser' and it's working with Firefox as expected (Firefox was also a possible choice).
