How to stop infinity loading of a thread please?

Since we cannot post on the “Tips on using the site” forum my next option is to post here.
When I open the last post of a long thread, and scroll up, it keeps on scrolling up until all the 100s of posts are gone, until I get to the header. Is there a way to change this to a style with only a several posts per page? I would prefer a setting that allows you to go to the header without having to scroll up until years of posts are loaded.

On all threads, you’ll see two dates on the right side, next to the last post. Click on the “date started” (see arrow!) and you’ll be returned to the OP.
