If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Ok my connection is fine,i can go onto other pages and i deleted all my cookies.
Only protection i have is Norton and weird thing is before the downloads were working perfectly fine but then out of no where the error started popping out. Also if my computer was protected by a proxy and stuff how would i disable it to let my firefox access?
