Yeah you want Livemarks on Firefox (add-on) so an RSS feed symbol will pop up when it detects a site has at least one, and any hyperlinks to RSS feeds will open in browser properly instead of showing you some raw text. You can also drop the site's URL itself into an RSS feed such as FluentReader or RSSGuard. I'm gonna have to push Flare Android app here because it threads everything together across RSS and social media, making it a no brained. Also the share button works for adding RSS very much a deal breaker with these apps. Feeder is also good I use it for all of the github and codeberg shit and nerd blogs etc. Shame it doesn't support multiple OPML files well. RSSGuard has the best organization, nexted folders that show their child folders' contents (looking at you Thunderbird 😐👎). Lets you set different rates for each website to update. Which in the age of rate limits should probably be the first thing people do but so far I haven't had problems with that. Maybe when we get into thousands of YouTube music pages.

Stuff like RSSHub is for ppl who want their own cacheing and redistribution and to preprocess the feeds with searches and stuff. I mentioned that here but don't worry abt that, it's for making stuff work that doesn't want to show an RSS feed or it was set up in like 2006 and they think it's not dogshit because technically it gets lots of hits. This is just to be very extensive but I:m making it sound too hard so I'll stop here.
