I have a local html page devoted to news. An entry for a specific site will see at least two urls: The main site's URL and a link to it's RSS feed.
Linking to the feed directly was a great way to bypass all the modern garbage on the home page to see a simple list of articles (not unlike HN's home page). It's borked now...
None of my RSS links render. Chromium was very bad at this but at least it rendered a few (a couple of examples below), FF64 doesn't render any (in any form):
http://feeds.arstechnica.com/arstechnica/index
https://feeds.feedburner.com/ItsFoss
A huge part of my ability to enjoy the web has just been destroyed.:( I'll have to test this on other browsers...
edit (update): both sample links above are working now (odd). Most others with XML, RSS, Atom extensions do not render (FF offers to open in external app or save).
