I recently ran into a couple of problems with Sage, the lightweight feedreader extension for Firefox. Sage wouldn’t parse some of my feeds.

One of the problems was down to Sage not understanding the URL for the feed because the “feed” protocol had been added to the address. For example:
feed:http://www.domain.tld/myfeed.xml

You can get Sage to behave by simply removing the feed protocol from the start of the URL. Easy peasy!

Incidentally, I submitted a bug report on the Sage project about the feed protocol and it should be straightforward to solve, so I’m hoping Sage will soon be updated with a fix.
