UltraSurf is freeware that can be used with Internet Explorer and Firefox. It gives you the ability to browse the Internet anonymously and securely by hiding your IP address behind the proxies it provides. With UltraSurf, you also get to overcome any Internet restrictions hindering your browsing freedom. When using UltraSurf, the software is set to work on “Auto-Detect Proxy” mode by default; however, if you want to use UltraSurf in “Manual Proxy Setting” mode to add your preferred proxy, you can swiftly set up a proxy in UltraSurf by editing the web browser’s proxy settings.
