Are you trying to view an RSS or Atom blog feed in Firefox, and instead of a clean, readable layout, you’re greeted with raw XML code or even a blank page? You’re not alone—and there is a fix!

Since Firefox removed native RSS feed support a few versions ago, users have been struggling to access and read blog feeds without relying on external apps. But don’t worry—this guide will help you restore feed functionality directly in your browser.

🔍 What’s Going On?

Firefox used to include a built-in RSS reader and preview tool; however, this functionality was deprecated starting with Firefox 64. Now, when you visit a blog feed URL like https://example.com/feed, Firefox will simply show the raw XML file. That’s not very helpful if you want to browse updates or subscribe with ease.

✅ Solution 1: Install the “RSS Preview” Extension

The easiest way to restore proper feed viewing in Firefox is to use the RSS Preview extension. It adds back the essential functionality to preview, subscribe to, and view feeds just like the old days.

🔧 How to Install:

  1. Go to the RSS Preview extension page on Mozilla Add-ons.

  2. Click “Add to Firefox” and confirm.

  3. That’s it! Now, whenever you visit a blog feed URL, you’ll get a clean, readable preview and a handy “Subscribe” button.

Tip: This extension supports both RSS and Atom feeds, so you’re covered no matter the format.

🔁 Alternative: Use a Dedicated Feed Reader Extension

If you’re looking for a full-featured in-browser reader, here are a couple more extensions worth trying:

📥 Feedbro

  • Download Feedbro

  • Acts as a complete RSS reader built into Firefox.

  • Lets you subscribe, organize feeds, and read articles all in one place.

📬 Slick RSS

  • Download Slick RSS

  • Simpler than Feedbro, but great if you just want basic feed management.

📱 Prefer a Web-Based Reader?

If you don’t want to install an extension, you can still use online RSS readers. Just copy and paste the feed URL into one of these:

You’ll need to create an account, but they offer syncing, categories, and other advanced features.

🛠 Bonus Tip: How to Find a Blog’s Feed

If the site doesn’t advertise its feed URL, try adding /feed or /rss to the end of the domain. For example:
