Firefox register newsblur as an rss reader doesn't work

 TypeError: navigator.registerContentHandler is not a function[Learn More] common.js:2470:310


Firefox 62.0.2 (64-bit)
MacOS 10.14 (18A391)


navigator.registerContentHandler() was removed in Firefox 62.


Is there a path to registering Newsblur as my feed reader in Firefox?


you can try changing the keys in about:config


I tried this (in many permutations) and was unable to get this to work. Clicking a feed link in my browser now does nothing but leaves an entry in the console of: “Navigated to” while remaining on the current page.
