I used to be a loving VimFX [0] user. It had intelligent link hints (essentially, links it thinks you are likely to want, e.g. because they're big, get single-key shortcuts). The scrolling was actually native, as in equivalent to hitting the arrow keys. I don't think any of the other Vim emulator plugins ever replicated that. Vimium doesn't, Tridactyl doesn't, and Vim Vixen was horribly broken.
Apparently VimFX still runs via some hacks on modern Firefox versions? The last release was even in 2022. Maybe I should give it a try again.
It's more about 'feeling' native than actually being native. I managed to reinstall VimFX and it doesn't quite scroll like the arrow keys, either. But its scrolling speed still feels more natural than either Vimium or Tridactyl, although it's a bit slow.
Tridactyl's huge jumps are annoying to me, as is Vimium's excess smoothness. In Vim, I hit j once to scroll one line, same as <down>.
