Firefox + McAfee = bad?

i just installed McAfee antivirus/firewall on my pc, and everything was running fine until recently that it started giving me warnings about firefox everytime i opened it. already clicked on fully allow and added it to the trusted programs to access the internet list on mcafee. and it still gives me a warning whenever i open it. anyone knows what could be causing it?

Fag, stop using that broken piece of shit. It renders pages like crap and is crippling development of Internet standards because Microsoft doesn't want to fix its fundamentally broken rendering engine.
