How to Add New RSS Feed Into Feedly for Firefox

Update April 2019: Thought I would add that for Firefox 63+, RSSPreview also allows you to preview a feed directly in Firefox and view it’s source code if you want. In order for this to work, you would need to select RSS for the Subscribe Using option in Awesome RSS‘s options.

Update December 2018: For Firefox 63+ they’ve removed most of the RSS handling code and adding these about:config entries don’t do anything now. See: Mozilla plans to remove RSS feed reader and Live Bookmarks support from Firefox – gHacks Tech News. Using Awesome RSS still works though.

Update November 2017: For Firefox 57+ there is now the Feedly Subscribe Button or Awesome RSS extension (which now has a Feedly option). The about:config modifications shown below also still work to add it to Firefox’s list of handlers.

Update November 26, 2013: Feedly changed their URL. They took “cloud” out of the URL. So, the correct URL is now: which I have altered below.

Update July 3, 2013: After reading How to add web services to the RSS signup page? on the mozillaZine forum (and comments below), thought I would put what needs to be done for Feedly here (after they finish re-doing the Firefox extension, none of this should, hopefully, be necessary):

To add a feed handler manually,

  1. Type about:config in the address bar and press Enter.
  2. Press the big button to bypass the warning.
  3. In the search bar, paste browser.contentHandlers.types. and note the highest number of the preferences listed (e.g. browser.contentHandlers.types.5.title)
  4. Right-click somewhere in the lower pane and choose New, then String.
  5. Create preferences with the following values, replacing 6 with the appropriate number in your case. %s is a placeholder for the feed’s URL; Firefox will send that URL to the feed reader website.
    • browser.contentHandlers.types.6.title Feedly
    • browser.contentHandlers.types.6.type application/vnd.mozilla.maybe.feed
    • browser.contentHandlers.types.6.uri
  6. Restart Firefox for the changes to take effect.

You should now see a Feedly option in your drop-down list for feed readers. πŸ™‚

Update June 25, 2013: Thought I better update this post. Currently Feedly is up to version 16.0.528 of the Firefox extension and I am now running Firefox v22.0. Also, it looks like my account is now completely handled by the Feedly Cloud. As such, my URL to add a RSS feed into Feedly has changed from what is used below. The current URL which I now use when making the bookmark is:ΒΒ . It also seems like the extension is more of a front-end to the web only version of Feedly that adds some additional abilities over the website by itself. Hopefully this helps others that have been completely moved over to the Feedly cloud. πŸ™‚

Update March 28, 2013: Feedly just released version 14.0 of the extension for Firefox on their site. It does seem to correct the problem with adding new feeds and does seem to fix the Google+ button issue when trying to share with it. It’s got some of its own little quirks (which some may not even notice). Version 10.2 is still available on the Firefox Add-On site (actually, they keep most of the older versions archived).

As most are aware by now, Google has announced that as of July 1st, Google Reader will be shutdown. I have been testing out Feedly as a replacement. If you’re reading this then odds are that you’ve already installed the Feedly Extension for Firefox. At the moment it’s basically a front-end for Google Reader and syncs its content with Google Reader. Changes made in Feedly will appear in Google Reader and visa-versa. More information can be found here on Feedly’s blog: Transitioning from Google Reader to Feedly.

The biggest problem that I and many others have run into is adding new feeds directly into Feedly. The normal process in Firefox usually displays an error like this. Anyway, here’s the easiest way that I’ve found to do it.

First, create a new bookmark of one of your existing Feedly pages or just make a new bookmark of anything really. Then, right-click the bookmark and select properties so that the following dialog is shown:

Bookmark Properties

Like I’ve done, change the Name to something more meaningful, and most importantly, change the Location to be sure to add the “%s” at the end. Then add a keyword, such as “f” like I have done, and click Save. (Note: see the June 25th update at the beginning of this post for the current URL if you’ve been moved over to the Feedly Cloud.)

Now, simply preview the RSS feed you want in Firefox using the normal method or copy the link to an RSS feed. Then in the address bar, either insert a “f(space)” (or whatever keyword you decided on) in front of the URL if it’s already showing or type “f(space)” followed by the URL to the RSS Feed:

Address Bar

After pressing enter, you should see the new page being displayed within Feedly’s context. At this point, just click on the green +Add button:

Add feed to Feedly

Success!! πŸ™‚ (oh, as of this writing I am using Firefox v19.0.2).

Update March 17, 2013: Another work-around is to simply refresh the browser using F5, the address bar’s refresh button, or Feedly’s circular arrow refresh button, if you see that unable to load feed error page. After refreshing it seems to properly decode the URL and display the appropriate content to then add.

How to Remove the Chat Widget While Watching NASCAR RaceBuddy or Media Center

If you’re like me, you could probably careless about the social media chat widget thing that is to the right of the NASCAR RaceBuddy and/or Media Center video streams. I do my chatting in a separate Twitter tab within the browser or a separate Twitter application such as TweetDeck. Not only is the chat in these widgets less than desirable at times, but it also seems to cause the video streams to constantly lag and start/stop when the chat widget updates and scrolls items down/up. This is the primary reason I decided to see if I could stop the chat widget from loading in the browser. You can always move or resize the browser window to hide it if that’s all you want to do.

My main browser is Firefox (version 10.0.2 as of this writing) within Windows XP Home/SP3 and this is what I did: After poking around in the source code for the page, I found a JavaScript file being loaded that most likely handled the chat widget. Using Adblock Plus, I added a custom Ad Blocking filter to block || from loading. This is what the Adblock Plus Filter Preferences dialog should look like after adding the filter:

AdBlockPlus Filter Preferences

Success! No more chat widget on those pages and the video was much smoother afterwards. Note: this will affect any webpage that uses the same script to display a similar chat widget.

I haven’t tried it yet but I suspect adding an entry to the Windows’ HOSTS file for to point to would have the same effect and would prevent all browsers from showing the chat widget (or anything else associated with that sub-domain).

My plea to NASCAR.COM and TrackPass (RaceView) Developers

It’s probably a good thing I waited until today to write this; otherwise, it would have been full of many colorful words. πŸ™‚ This is a follow-up to my last post. I tried to run NASCAR.COM’s RaceView during the Michigan race this past Sunday and all I got was either a window with “loading” at the bottom or just a solid white window. This occurred in both Firefox and Internet Explorer. I opened up the Java console in both Firefox and IE and it just had a Java error of a Null pointer assignment:

 at com.sun.opengl.util.JOGLAppletLauncher.start(
 at sun.plugin2.applet.Plugin2Manager$ Source)
 at Source)
Exception: java.lang.NullPointerException

Yes, I did try to reload several times. So I gave up and just started PitCommand to listen to Dale Jr’s audio. I did have to start it in IE first before the audio would work in Firefox and I just didn’t care to investigate this further. I was frustrated and missing the race. Before you ask, I do meet their minimum system requirements.

Now, I don’t mind troubleshooting problems; however, I do not want to do it during the actual race! It totally ruins the fan’s experience. How can you expect fans to search knowledge bases and forums, reinstall Java, plug-ins, audio and video drivers, and do whatever else might be potentially involved? It boggles my mind that there isn’t a race simulator that we can test these applications with during the week. If I was a NASCAR website/TrackPass developer I’d scream for this. I am quite sure the website team has no desire to fix the software during races either (I only hope they at least have some internal system to do this). Normally I wouldn’t give a flying fruitcake about it, but I am paying more for TrackPass than I am for my webhosting here that my blog, among several other sites, is on. The IndyCar RaceControl works (yes, they do loose timing and scoring sometimes but that’s an issue at their end when it happens) and it’s free.

This will probably be my last season to subscribe to RaceView. If the preview works during next year’s Daytona 500 then I might reconsider; otherwise, I’ll just stick with the scanner.

I welcome any comments about other’s experiences and how you got it to work, if you did.

Getting NASCAR PitCommand audio working in Firefox

(If you’re having problems with RaceView, you might want to check out this post: Getting NASCAR RaceView Working with Internet Explorer 8)

During Sunday’s NASCAR race I was trying to get the audio working in NASCAR.COM’s PitCommand using Firefox (version 3.6.8 at the time). No such luck, even after disabling AdBlock Plus and enabling 3rd party cookies. So, I decided to try it in Internet Explorer 8. Naturally, it worked just fine. I tried it again in Firefox, and it worked! Hmm.. what’s going on here?

I knew that the audio stream was being handled by Windows Media Player since it was using the .ASX extension. I did have the Windows Media Player plug-in for Firefox installed. There’s an article at mozillaZine which gives information about it. In fact, my MIDI page is designed to work with it. Since it only worked after I tried it in Internet Explorer, I figured it must have triggered something or saved something into Temporary Internet Files that allowed it to then work in Firefox. Since WMP is a Microsoft program, it stores its files in IE’s Temporary Internet Files directory. So, I deleted the Temporary Internet Files using the Internet Explorer Control Panel applet. The audio quit working with PitCommand in Firefox again. I launched PitCommand in IE which worked and closed IE. The audio started working in Firefox. At this point I restarted Windows and went to Firefox first thing and the PitCommand audio worked.

It seems that some Javascript or other file that gets saved to Temporary Internet Files when using IE is letting the WMP Firefox plug-in to play the audio in this specific case. This leads me to believe that the code on NASCAR.COM’s site might be doing different things based on the browser it detects. Because I was sick of troubleshooting and missing the race I stopped here.

NASCAR.COM really needs to have a fake race stream during the week so that all of us, and them, can work on software issues then and not during the actual race! Who wants to do that? I also tried RaceView but it wouldn’t work in either Firefox or IE. I just got a blank page with a Java error on it. Early this morning I got a Java update (version 6, update 21) but I won’t be able to test that out till the next cup race.Β  πŸ˜•

How I got NASCAR RaceBuddy working in Firefox.

Update July 14, 2012: Thought I should mention that the issues I had below were under Windows XP Home/SP3. Currently, I have a completely new system running Windows 7 Pro/SP1 64-bit (hardware specs) with Firefox 13.0.1 and Adobe Flash 11.3.300.265 with Protected Mode enabled. I’ve never had a problem with RaceBuddy not working other than the Flash plug-in crashing once or twice; however, during some races, like today’s Nationwide race, no issues. This and the previous two versions of Flash have caused some grief amongst some users just watching normal videos in Firefox, Chrome, and even IE but nothing specific to just RaceBuddy.

During the NASCAR Truck race on Friday, NASCAR.COM made TruckBuddy available.Β  It was very similar to RaceBuddy they had last year during the TNT races. You get a choice of several live video feeds along with a mosaic feed of 4 video streams at once and a live chat feature.


When I first tried it with Firefox (version 3.6 or 3.6.2), the video portion did not work and the live chat portion on the right side would not work properly either. It would let me attempt to login via Twitter and provided the typical Twitter Allow/Deny Connection authorization window; however, upon returning to the application it did nothing and acted like I had never logged in.


I solved the video problem by disabling Adblock Plus on the NASCAR.COM site. Apparently, if the video advertisement does not play first, then nothing else will or at least problematically.

I solved the chat problem by enabling 3rd-party cookies which I have disabled by default (Tools -> Options -> Privacy). Upon further examination, I could disable 3rd-party cookies again if I gave exceptions to the following:


After the race was over, I re-enabled Adblock Plus for NASCAR.COM :). Hopefully this helps anyone else trying to get RaceBuddy working with Firefox should they have it again.
