We encountered this during our POC with one of our client the home page of our client doesn't display properly with Mozilla browser with the ie browser it okay. Is there a way to resolve this?
I got a similar problem with the 6.0.1 firmware. The main web page became blank and i had to reload it again ( only with Firefox / Mozilla ).
I solved this problem with an upgrade to 6.0.r5.
Hope this will help
