List Feeds oleh igorlogius

Detects and lists feeds (rss,atom,json) of a page. RSS and Atom feeds are still
a very useful method to keep up to date on news and other kind of information.
On many sites the feed capabilites are still available but sometimes badly
maintained, so that it can be hard to access or find these. This Addon tries to
make it easy to find all available feeds a site has to offer.

Usage: (Basic)

1. Visit a site which contains feeds for example:
   
   • https://blog.mozilla.org/
   • https://en.wikipedia.org/wiki/RSS
   • https://www.youtube.com/user/Mozilla
   • https://www.youtube.com/watch?v=4fviHC7xlX0&list=PLnRGhgZaGeBvDBzQGf4M8HIepPXA9cq-C
     
   • https://jsonfeed.org/
2. The toolbar icon will be colored when you visit a page where at least one
   feed is found
   
3. click on the toolbar icon, to show the feeds

Usage: (Advanced)
You can write your own feed probing / detection functions in Javascript The
supplied function must return an Array as URLs as Strings. Those URLs will be
probed via a HEAD Request and if the server returns a Content-Type which might
align with a feed object, it will be added to the feed list. Example functions
can be found on the github page (see. custom-feed-detectors.json)
Notes:

1. Can/Should i trust this addon? You can view the source code by either
   visiting the Homepage/Support Site or just saving/downloading the XPI (which
   is really just a ZIP Archive) and then extract it locally. The Sources in
   the XPI should be unofuscated and unminified (HTML,CSS and JS), so it's as
   easy to read as possible. Alternatives you can also use the
   CRX Viewer Extension by Rob W
   to inspect the XPI sources. If you have an questions, you can also open an
   issue on the support site and i'll try and answer to the best of my
   abilities. If you are no programmer and are still feeling unsure, you might
   want to visit one of the official or unoffical mozilla communities and ask
   if someone there with more knowlege can take a look. Examples:
   https://reddit.com/r/firefox , https://lemmy.world/c/firefox or
   https://chat.mozilla.org/#/room/#addons:mozilla.org
