Never ending scrolling
Every once in a while I'll visit a website that, even tho you scroll to what you think is the bottom of the page, when you approach that point, you see the scroll button jump up, and there is further room to scroll.
It happens occasionally on YouTube, but elsewhere as well.
I think I remember somewhere that there is a workaround for this, but first I want to understand if this is by design, perhaps because it's a way of restraining the given site from loading too much content at one time, causing CPU overload, leading to related issues.

Auto-loading more content is a website feature (implemented using a script that watches the scroll position) and as far as I know, there is no Firefox preference to disable it.
Firefox does have some preferences to manage "lazy loading" of some resources, such as images. But this is a separate behavior from fetching new HTML content into the page.
As long as you do not scroll down beyond a certain point then new content shouldn't load, so try to be careful with scrolling on pages that have this behavior. This is even worse if you use the mouse to drag the scroll thumb as in that case that case you keep activating this extra loading feature. I normally use the space bar or cursor down to scroll such a page (I encounter this on the Mozilla HG website).
