hi i have a lot of problem when using proxies with vip72 , or they are very very slow or maybe the problem is on my side. 1. how do you choose fast proxies ? by Reply or Up Time ? 2.when i put socks on firefox, i should choose socks5 or socks4. 3.on the 99% of the time no matter which proxy i choose, its very very slow and i give up and switch another one every 30 second. maybe the problem is from my side? firewall or something?
