I would like to configure Firefox to open RSS feeds in a web-based reader (Feedbin).
The default page allows me to change between 'Live Bookmarks', a native application, or 'My Yahoo!'.
It won't be surprising to hear that I don't use Yahoo, but this seems to be the default and only web-based option - how can I change that list, to remove Yahoo and add Feedbin?
On Mozilla Developer Network, there is a page describing how to add a feed programmatically from a web application - less than ideal, but better than nothing, so I tried it in the console:
navigator.registerContentHandler(
'application/vnd.mozilla.maybe.feed',
'https://feedbin.com/?subscribe=%s',
'Feedbin'
)
X "SecurityError: Permission denied to add https://feedbin.com/?subscribe=%s as a content or protocol handler"
