Reddit Minimizer by techsin

On Reddit threads comments are often where the good information is. And post or link is just a conversation starter. However since there can be 1000s of comments, Reddit has functionality that you can collapse them, so the comment and all replies to it minimize into one line. To minimize you click symbol [ - ] , left of author name of comment.
It's all good but when you click a link, it takes you to another page. And once you're done reading and you come back, all the collapsed comments would uncollapse and expand.
So when you navigate back your scroll position will remain the same but all expanded comment threads will push the comment you were at all the way down somewhere. So now you either give up or start the search.

Redditminimizer, prevents comments from expanding on navigating back. So this way you come back to the comment you left at. Which makes for much better user experience and less annoyance.
