You can toggle the feature on and off for the current page using the new tab you'll find on the Reddit tab bar.
Or toggle the feature for individual posts by clicking on the "x other submissions" label below each post title.

This is actually an interesting little extension. It does it's purpose. Useful for finding posts with more comments if you find a link on a smaller subreddit. There should be an option to turn it off though.
