Some web site owners try to protect the content on their site by disabling the right-click on the mouse button so you do not get the contextual menu to save images or look at page contents. While stealing images is not cool, neither is messing with my usual browser controls. If you run into this problem, there are a lot of ways around it. But here's one simple way. When you are on a site with the right-click disabled, copy the following text into the address bar of your browser and hit the Enter key:

javascript:void(document.oncontextmenu=null)

Once you do that, the right-click functionality of your browser should be restored.
