445657 - unable to registerContentHandler for rss feeds containing enclosures (podcasts & vidcasts)

Status: RESOLVED WONTFIX

(Firefox Graveyard :: RSS Discovery and Preview, defect)

Description

[Frank Lynch]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9) Gecko/2008052906 Firefox/3.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9) Gecko/2008052906 Firefox/3.0

In firefox 2 I was able to register content handlers for all rss feeds thru a bit of javascript like the following:

<input type="button" name="add" value="Add contnet handler to Firefox"
onclick="window.navigator.registerContentHandler('application/vnd.mozilla.maybe.feed',
	'http://domain.com/foo/%s','custom-handler');" />

When a user clicked on the button they would be asked to confirm & the handler would be available for RSS media including podcasts & video podcasts.

In firefox 3, this code works for regular rss & atom feeds, but the handler does not show up for feeds that contain enclosures eg: podcasts. 
I have tried using other mime types such as: application/vnd.mozilla.maybe.audio.feed and application/vnd.mozilla.maybe.video.feed in place of application/vnd.mozilla.maybe.feed but when I used them firefox 3 didn't add the content handler - i.e. you don't even get prompted to confirm that your adding a content handler.

Reproducible: Always

Steps to Reproduce:
described above in details section.
Actual Results:  
cannot add content handler for rss that contains enclosures - podcasts.

Expected Results:  
expected behavior to be the same as firefox 2.0 - registered rss content handlers should be visible in all rss feed pages including those for podcasts.

Just ran into the same problem.

I'm developing an internally-used feed reader for the company I work for, and we just added support to listen to podcasts inline. I was surprised to find out even if our users had added a feed handler (via registerContentHandler) our webapp did not show up as an option in the "Subscribe to this podcast using:" dropdown menu when directly viewing the url of the podcast

So, firefox 3 is not showing and web feed handlers for audio or video podcasts. I think this is a bug and could be fixed two different ways.

1. Add additional mime types for the registerContentHandler call to register webpages for audio/video podcasts.

2. Show application/vnd.mozilla.maybe.feed feed handlers in addition to the  applications a user configured for audio/video podcasts when viewing the feed for a podcast.

I think 2 is preferable, but either would be perfectly fine.

Do either of you still see this in Firefox 3.5?

Also, can you like to an example so that I can easily confirm this?

Yes, still a problem in firefox 3.5.2.

Visit a normal feed such as http://feeds.nytimes.com/nyt/rss/HomePage. Notice that the subscribe dropdown includes Bloglines, My Yahoo, Google, etc.

Visit a feed with enclosures, such as http://revision3.com/diggnation/feed/MP3. Notice that the subscribe dropdown does not include Bloglines, My Yahoo, Google, etc.
