I set up my FF useing apekillas method he posted. Grabbed a proxy from one of the lists in the sticky. I went to ipchicken.c0m and sure enough, it showed the proxy but when i went to whatismyip.c0m it showed my real ip and had a big red warning about a suspected proxy server being used. So I'm wondering if sites i intend on using this method with can see through the proxy or if they can tell if you're using one. I did clear all cache and cookies btw.
