Support for Firefox 4?

Hi all, Just updated to NIS 2011 and have been using Firefox beta for a while now (it’s currently at beta 4). NIS Indentity Safe toolbar does not show in FF4 and I wondered if there were any plans to make it compatible before FF4 goes final? Also, can anyone confirm that Norton IPS add-on still works in FF4? It doesn’t say it’s incompatible under add-ons but just wondered. Thanks for your help.
