Twitter loses your scroll position when you go from a Tweet thread to a reply thread, then come back. This is what the extension fixes.

Twitter does keep your scroll position when you go from a "top-level" view ("For you", "Following", ...) to a Tweet thread, then come back.

I cannot reproduce this, but I don't doubt it happens for other users. Guess I am in the lucky bucket. Maybe Firefox users get an older version without some new "improvements". :)

Edit: Nevermind, it happens to me as well, I just never noticed.

How interesting. I experience this problem on both Chrome and Firefox (v121.0.1 on Ubuntu 22.04).

I am mildly curious about why only a subset of Firefox users are experiencing this. Do you mind sharing your Firefox version and OS?

I went to do a sanity check using your steps and unfortunately I missed the problem the first time around - when I go to a tweet thread, then a reply thread, then come back to the tweet thread, it is indeed scrolled all the way up to the top. So I was wrong, I am affected by the same issue, I just never realized it until I went looking for it. One positive I'm taking away from this is the realization that I use Twitter less intensively than I thought, because I wouldn't have noticed this without the explicit steps I don't think. :D
