Haven't checked on it since about mid last year but Facebook settings didn't work with it for me.
LinkedIn has also been especially hard to find a good blocker for to remove the sponsored/suggested posts from the timeline (it's just full of garbage engagement bait hot takes).
I just vibecoded a tampermonkey script to block scrolling on Instagram and also block reels. I also had it redirect from the `/reels/` URL to `/reel` which is just the single video view (for when friends link me memes), but it seems they removed that.
