IP masking

I have an account on mediafire (http://www.mediafire.com/) and I've used it a few times. Recently I just get a blank page when I try to open it, without any error reports. I read somewhere on the Internet that they started blocking many countries (by IP) recently (though I can't find any more info on that, like the list of blocked countries). I tried to bypass that by using proxy servers to disguise my IP. I tried many (mostly from the lists on this site : http://www.publicproxyservers.com/ ) but none of them worked properly. Most just didn't do anything (meaning that I would have to wait indefinitely for any site to open), some opened the site, but the logon procedure didn't work, and one worked perfectly, until I tried to upload a file, and then it reported that I can only use http through that proxy. Using that same proxy later, I opened the site and got a blank page again, like mediafire had somehow seen through my trick ?
I'm using Win XP and Firefox 1.5, please tell me if you know of a way I can use mediafire, because I really need it...
Thx.

Public proxies are generally hacked/stolen servers. Don't expect them to be fast at all, or to work for long.

better use TOR

I agree that tor would probably be your best and most reliable solution.

For more information: http://tor.eff.org

go to google and type proxy toplist

tor ftw.

Search for free proxy or use this linke www.proxy4free.com

TOR sounds nice .. or use hideIP as well

i've been wondering about internet anonymity myself, but never done anything about it... i will check out TOR, thanks
