* I really just want pocket as a bookmarking tool than the web reader. The web reader works, but it's very bad in cases with a lot of embeds/code snippets. If a site is pay-walled, only a small section is available in Pocket. I usually open the actual page in this case than read in pocket.
* Some links I added a long time ago are permanently lost because the original page got taken down. It'd be much better if a permanent snapshot was taken(including all the images, this is pretty easy to do with something like https://github.com/gildas-lormeau/SingleFile) of the page and is available even if the original page is lost.

There's an extension called floccus [1] that can sync bookmarks between numerous different browsers (including both Firefox/Gecko and Chromium/Blink based) and plug into a user-controlled NextCloud [2] or Linkwarden [3] instance running on a local homelab server.
However, I try to minimize the number of installed extensions to reduce my own browser fingerprint. As others have replied, Firefox sync works across most of today's popular downstream shadow-forks of Firefox (as in, forks that shadow the Firefox releases rather than truly forking the code). If you don't want to give Mozilla's enshittified corpse your email (I don't either), just use an email service that supports aliases to sign up for Firefox Sync... Which is in any case a good idea generally: no two of your important online accounts should point to the same email, even if behind the scenes the aliases are all routing emails back to you.

I'm surprised no one has mentioned Surfingkeys https://github.com/brookhong/Surfingkeys. I switched over from Vimium a couple years ago. I think its more performant than Vimium and also allows you quite a bit more flexibility in your configuration.
I prefer and recommend browser add-ons over Nyxt. You'll get more compatibility by being able to use Chrome/Firefox. You'll also have a much higher chance of being able to use the same environment at work - since you can typically still install browser add-ons in developer mode even if you aren't able to get rights to install apps.

Project mention: The Return of Digg, a Star of an Earlier Internet Era | news.ycombinator.com | 2025-03-05
It seems to be OK for me, but I am using https://redditenhancementsuite.com/
So many that makes a difference. I think it forces the old interface. Like my URL isn't even old.reddit, but all I see is the old interface. Or maybe I don't use subs with newer posts types that are not compatible with old?

Works fine. Reverse chronological sorting with just who you follow.
For automated... apart from self host RSS options or nitter instance, neither of which I've tried...
For semi automated I have a manual but not too laborious google sheet:
