That's my question too. My ISP says they are using transparent proxy, the lagado transparent proxy cache test is also showing that I am behind a transparent proxy. I cannot resume using Jdownloader. I cannot resume using IDM. Then how can I resume via browser? If you are such an intelligent guy, why don't you answer that?

And you can start by helping yourself. No use sitting behind a computer screen and acting like smarty pants to some random guy on the internet, whom you know nothing about. So far you have been going on and on about that Windows firewall, which I have conclusively proven to be not the troublemaker.
