Newspaper Reading..

Hi, my local news paper is publishing an on line version.. requires me to zoom & scroll.. but on Firefox Android version when I zoom & scroll, after I remove my finger from the screen, the display reverts to top left corner of the image... The zoom & scroll function works perfectly on Google Chrome... Link. But needs a subscription... https://edition.pagesuite-professional.co.uk/html5/reader/production/default.aspx?pubname=Largs%20and%20Millport%20News&edid=f3655f15-2611-47a7-839b-694ef61e9fb2
