Some browsers can open and view PDF file directly within the browser itself Internal PDF viewer, open PDF in a new tab in browser. So that PDF reader software is not necessary for open PDF file from internet. I tested Chrome 27.0 and Firefox 26.0 can open PDF file within the browser itself. Older browsers may not support open PDF within the browser itself, e.g. Firefox 3.6 download file now
