If I change the proxy ip in firefox not change it for other software that connects to the Internet?

No, only in Firefox. I tried hundreds of proxy servers for many months. All I have of it was a great frustration, as it hangs in the short term. Well, I have one more thing and it was a virus that destroyed one my HD. Even when he worked for a time was slow and do not support all the website features. My friend said in Riyadh on personal http://www.surfbouncer.com VPN. It's kind of an expert to unblock sites because they live in a place to hang it so much fun. Anyway, I tried a few months ago and has been working all the time. I have not been blocked since then, and the sites are 100% functional. With all the personal VPN works as supposed. Once connected, you do not even know it's there. It is not free, but it works perfectly.
