First you need to get WebMask up and running on your machine.
In this beta version, there is no automatic installation program.
Instead, you have to unzip the WebMask archive file, and run WebMask.exe. You will then see the WebMask icon in the task bar. Then all you need to do is set your browser up to work with WebMask. This is described in the next section.
Once you have set up your browser to work with WebMask, you need to always have WebMask running. Otherwise you won't be able to access any web pages. Because of this, you will probably want to put a shortcut to WebMask in your startup directory, so it is always running.
