Just recently I've noticed from my Comodo Firewall that I have strange outbound connections when using Firefox. It keeps secretly downloading nothing. Every time I download any type of file I get strange ports using my bandwidth and not sure what its using it for. I blocked all of the unknown IP Addresses the first time and still could search the internet and do everything else normally. But eventually new ones will pop up again.
This may have been going on for a while (2 years!) but I was able to find out because of the new Comodo. My downloads are 30kb if Firefox connections are left alone when normally it would be without it 250 to 400kb before it came to this point. That's when I noticed the strange connections and after blocking them my bandwidth jumped per download to 750-800kb!
I'm happy but this is tedious because new addresses keep popping up and I have to keep blocking them. What is going on? Anyone else have this problem? Is there a better way to defend against this?
