Ultrasurf is a free software that enables users to visit websites safely and freely through a secure encrypted tunnel. It is a small file, and no installation is required.
Ultrasurf runs on Microsoft Windows. It supports Internet Explorer by default. You may also use Firefox (click here to download the Firefox add-on). To use other browsers, you need to manually set up proxy to use Ultrasurf. Certain anti-virus programs may prevent Ultrasurf from downloading or starting. If you encounter this problem, you may need to accept Ultrasurf as an exception, or temporarily disable your anti-virus software.
If you are having difficulty installing or using Ultrasurf, visit our User Center. You may also view Freedom House's video tutorial here.
