Firefox Browser Version 114.0.2 64-bit

Visit lemmy.world and under local or all tab, new posts keep appearing at the top of my feed. Sort type does not matter. The posts that get loaded at the top consists of many posts from a specific community. After 10 seconds or so, it loads a new set of posts from a different community.

This causes my computer cpu usage to skyrocket and makes my computer stutter. I also can’t view pictures on the feed because they will close when new posts are loaded. Any ideas?
