How to Get RSS Working in Firefox 64

As of Firefox 64, the ability to preview RSS feeds natively has been removed, which kind of sucks. I get why they did it though (or do I? Hmmm…).ย  Anyway, to get the functionality back, you need to install one or more add-ons.ย  Since Firefox 63 came out which lost the ability to detect RSS feeds, a lot of RSS feed related extensions have started appearing.

Firefox RSS Detection using Awesome RSS

At the moment, I am using Awesome RSS to add an RSS Feed indicator to the Location bar andย RSSPreview to preview the feed much like before.ย  For this to work, the RSS option needs to be selected in the Subscribe Using option of Awesome RSS. There might be a better option but these work for now for my needs. For those that use Feedly, Awesome RSS does have a Feedly option as well.

Hopefully this helps anyone that’s missing the RSS functionality. ๐Ÿ™‚

Migrating to Firefox 57 and Web Extensions

I’ve had the latest Beta Version of Firefox installed alongside my normal install for some time. Well, actually, I currently have Firefox 56 32-bit, 56 64-bit, ESR 52.3.0 32-bit, and 57 beta4 64bit installed. ๐Ÿ™‚ All of them are using separate profiles. Anyway, since my beta install has been updated to Firefox 57 (beta 4 now), I’ve been using it as my primary browser to test things out and see if I can tweak it to match my normal install.

The biggest change is that it will only allow add-ons made with the Web Extensions framework to load. All Legacy extensions will be disabled. Fortunately, some of my extensions already had an updated version; however, many did not. Some extensions may be impossible as a Web Extension and have the same functionality. So, I began searching for replacements to achieve similar results. I have changed my Firefox Configuration page on my main website to show my current setup. You can visit that page to see what extensions I’ve got and the tweaks I’ve done with userChrome.css. Lot’s of Googling during this process LOL. I thought about listing my before and after extensions to show what I replaced with what but it’s all still in flux. We’ll also have to see if everything behaves the same once version 57 is released in the normal channel. Oh, for those that used Classic Theme Restorer, you might want to check out Aris-t2/CustomCSSforFx: Custom CSS tweaks for Firefox 57+ for what might be possible. I did go ahead and remove CTR because there was no need to keep it for a possible update.

Here’s what mine is currently looking like:

Firefox 57 Beta Appearance

Things have turned out not as bad as I had feared and I am happy with things so far and will continue to tweak things and see which replacement extensions work the best. ๐Ÿ™‚ If I think of something else I’ll update this post or make a follow-up one.

Recording MP3 Versions of MIDI Movie Themes

Because Firefox has basically stopped all plugins from working except Flash since version 52 and workarounds failing with version 55 (ugh..), none of my DVD and Blu-ray pages that have an embedded MIDI player using the Microsoft’s Windows Media Player plugin work any longer. So, I decided to record MP3 versions of them which can be played using a standard HTML5 <audio> tag that all modern browsers support.

Audacity and XMPlay

Originally, I used Cool Edit 2000 which I’ve had a licensed copy of for some time. I recorded The Best of Benny Hill theme using it. Since then, I’ve been using Audacity to record the audio while using XMPlay to play the MIDI file. I then exported the audio as a MP3 using the Lame library. I used the Extreme quality preset during the export. So, now on pages like Star Wars IV: A New Hope, there’s a MP3 player as well. Since I’m using the MediaElements.js HTML5 video player on these pages, I decided to their MP3 player also.

Now I need to figure out what I’m going to do with my General MIDI page, if anything.ย Hmmm… 😖 For now, at least, the Windows Media Player plugin still works in Firefox ESR 52.

Website Changes During April 2013

Main Site Updates

Yesterday I noticed that my YouTube players on my Entertainment and NASCAR pages had quit working. They were completely blank. My guess is they finally pulled the plug on these old style players. So, I grabbed the latest embed code, using iframes, for my playlists and replaced the old players. I guess the added benefit with these newer players is that they will detect if your browser supports HTML5 or not and display the appropriate HTML5 or Flash based player. You need to be part of YouTube’s HTML5 Trial for it to show the HTML5 version, provided your browser supports it.

Speaking of HTML5, Firefox 20 added support for videos encoded with h.264 in certain operating systems (namely Windows 7 and above at the moment as the OS comes with the codec). This is disabled by default, however. You need to go into about:config and set media.windows-media-foundation.enabled to true.

Gallery Updates

April 22, 2013: Gallery released version 3.0.7 which I have since upgraded my galleries to. It addressed a couple late-minute security vulnerabilities that were discovered.

It seems that not long after Gallery v3.0.5 was released that Gallery v3.0.6 came out to fix some bugs. So, I’ve updated my galleries accordingly (actually did this a few days ago). Exact same process as before.


That’s all for now. Anything else I do this month I’ll update this post. ๐Ÿ™‚

How to Add New RSS Feed Into Feedly for Firefox

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: http://feedly.com/#subscription/feed/%s 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 https://feedly.com/#subscription/feed/%s
  6. Restart Firefox for the changes to take effect.

You should now see a Feedly option in your drop-down list for feed readers. ๐Ÿ™‚


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:ย http://cloud.feedly.com/#subscription/feed/%sย . 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. ๐Ÿ™‚


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 http://www.feedly.com/home#subscription/feed/%s 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!! ๐Ÿ™‚ (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.
