NetworkManager and Vodafone Mobile Connect

[Sam Przyswa]

Hi, 

On Ubuntu 9.04 I have problems with NetworkManager and Vodafone Mobile Connect (Internet via mobilephone) when it connect to internat via ppp interface Firefox doesn't see the opened connection. Firefox only see the connections opened with NetworkManager, NM is very unstable and buggy, on my desktop I had to remove it and configure by hands the /etc/network/interface.

How to fix the problem and make Firefox working with VMC ?

Sam.
