Hello Max, i believe that all websites now produce like 3 versions of their webpages, ie computer, tablet and smartphone. This is because the regular pages we see on the computer are too large for smartphones. That being said, i dont know how the page sharing feature in FF works towards modifying the html/css codes to display correcting on a smart phone. Perhaps, if you send a weblink to the phone instead, i think this would be a better way to go because the webserver would then know that a smartphone is clicking on the link. But all the above are just food for thought.
