Hi - after the most recent update to my mobile Firefox browser (on a Galaxy GT-19300, running Android 4.1.2) its started to cut off the top of my content on certain websites I've built using a full screen background slideshow: www.seanalexander.tv www.blackbough.co.uk www.thelittelthai.co.uk www.luckysevencaps.com . These are all fine on Chrome and Bing on my phone, and they're Ok on my desktop's Firefox, Chrome etc.... any thoughts? Thanks, Sean.
