I’m no html type code expert, but I do code a lot in other languages. I used f12 on a browser to look at what was going on, on the reddit sites and I have never seen such spaghetti code and layers upon layers of adjustments. I have no idea what they are using behind the scenes (php/js etc, again not my expertise) but it has to be an absolute shitshow.

On old old, and old new, I used to use an element picker in uBlock origin etc, to just remove all the bullshit that annoyed me. This actually sped things up! But its not perfect.

Oh this reminds me, if you are trying to get to new.reddit, for the old-new page, I had to delete all those elements as well, then goto new.reddit fresh and sign in. Then do the element pick again.
