I have android 4.4 on a nexus10 and I believe my browser version is up to date. In order to test my website on mobile devices I have created a page within my site with a fixed width meta viewport tag as follows: <meta name="viewport" content="width=799" /> On first loading the page, the width of 799px is correctly applied and the layout of the page is as expected. If I navigate away from the page and then return by the back button, my viewport width is lost and the page is displayed at 980px, I believe this is the browsers default viewport. To restore the correct viewport width of 799px it is necessary to refresh the page. I have been testing for some months now and I don't recall this behaviour in the past? None of the other mainstream mobile browsers exhibit this behaviour, they all work fine. I would appreciate any suggestions as to the cause and/or solution. Thanks in advance. Martin
