I use to use a browser extension that would redirect back to old reddit for that. it was very annoying

If you're tapping on the old ui already and trying to tap on links, I've found that if you tap on the 'comments' button, you'll stay in the old ui.

I've been using the 'Old Reddit Redirect' extension in Firefox for a couple of years now.

I don't have to worry about typing old. in front of reddit links, and it bypasses that attempt to redirect to new reddit.

You can also add https://webcache.googleusercontent.com/search?q=cache: before the reddit link if the post isn't on the wayback machine for whatever reason.

This is great. Until the Fediverse amasses more content, Reddit is still the best way to get answers from Google that aren't just SEO nonsense. Great way to still use Reddit results without using Reddit.
