Smart firewall blocking firefox 30 browsing and cannot configure program rules

Hi

 

When I opened firefox this morning, it upgraded to FF30.

 

After that, I cannot browse any websites on FF at all. Can on IE and chrome so thought it was an issue with firefox.

 

However, if I disable the smart firewall in Norton FF happily browses to any website. Enable smart firewall again - nothing. Disable smart firewall - no issues.

 

Having proved that the issue is the smart firewall, thought it would be a simple job of configuring the program rules accordingly. However, every time I click on configure,  Norton just starts not responding. Left it for about an hour with no sign of any movement. Rebooted, and exactly teh same issue again in all respects - Norton just sits there not responding.

 

Having no issues with anything else - internet working fine.

 

Any ideas please?

 

Thanks
