Does your instance have a mlmym interface? If not, you should ask your admins to add it.

It's not the full RES, but it at least gives you the "old reddit" format. Most of the large instances have it, like old.lemmy.world and oldsh.itjust.works.

Good i miss that too. Have you tried something like hoverzoom to fill the gap? That's what i did anyway and it works for all sites not just reddit. It feels like a core browser functionality to me now
