There are some pages that defines page or frame size with pixel size. If that page is designed for PC, that size is sometimes greater than the display size for small displays, such as smart phones. If frame tag is used like this: <frame .... noresize="noresize" scrolling="no">, Firefox cannot display full view of page and cannot zoom also. I think this behavior is correct as definition of HTML. But, it also means that Firefox cannot scroll out from the display nor zoom. I think this is problem for using Firefox on small display devices. I want to know the way to display full view and zoom for such page. Default Android browser and other browsers have such capability. Can you tell me the ways? PS. Sorry for my poor English.
