RightLynx, a Firefox extension, displays a Lynx view of a web page via right-click, toolbar button or Tool menu.
With just one click and without leaving the page (RightLynx opens in a new, small window), preview the page you are on with a Lynx Viewer.
You can see what what a page will look like when viewed with Lynx, a text-mode web browser. It is also presumably, how search engines see your site. In addition, it can help determine if web Seiten are accessible to the vision impaired
