I use RSSPreview for this. If a feed is available and you click its icon, it gives you a menu where you can select a feed to visit. RSSPreview basically changes how feeds are displayed inside Firefox.

I'd like to note that RSSPreview restores features that were removed in Firefox 64.
And by "changing how feeds are displayed", it applies an XSL Transformation to display the feed as HTML (instead of XML) in the browser. XSL Transformation is pretty neat, you can use it on any XML document such as your own RSS feed, like I done on mine.
Dope, I still love RSS+Atom
Cool, I've been using RSS Launchpad because it was the only one I found to also work on the android version of Firefox, but I'll take a look 👀
Nice, I thought something like this existed natively on some other chromium browsers too. Convenient it can be added to ff now.
i just added it and it doesn't show a lemy feed; how did you get yours to work on lemmy?
Hmm, I didn't do anything to make it work. Maybe try a hard refresh (Ctrl+F5).
If it is just Lemmy which doesn't work for you, then here's the URL for Top Twelve Hour sorting: https://lemmy.ml/feeds/all.xml?sort=TopTwelveHour
shutting down firefox and relaunching it made it work.
