I noticed this change of behaviour after a security update. Its most likely not fixable.

For some reason, whenever I use the back button or refresh button, it has started going back to the top of the previous page instead of to the point on the page where I was. What could cause this and how can I fix it? It did this about a month ago also, but it seemed to fix itself after a few days. Thanks
