Do you mean when you open something from the page you were on?

I get around this by; When I find a link I want to check out, I open it in a new tab/window. Then when I am done, I close it and am back where I started

Thanks for replying. The problem is not with opening a post. The problem is just with scrolling through the list of posts. After the first couple of screens the screen pops back to a previous post and continues to do this. The behavior is quite different with Chrome for example. After scrolling a few pages the browser pauses as if loading more posts and then continues normally.
