If you are a Firefox user and also an avid RSS feed reader, one thing you will notice missing from recent update of Firefox is the RSS Feed icon that uses to reside at the right hand corner of the URL bar. According to the Mozilla developer, the removal of the icon is because it is seldom utilized and it serves little or no purpose. Whatever the reason, the feed icon is no longer available in the URL bar now. Luckily you can still get it back through a less elegant way.
1. Open your Firefox browser. Go to “View -> Toolbars -> Customize”
2. Scroll down the list to find the RSS feed icon. Drag it to the top toolbar, either to the left or to the right of the URL bar. Click the Done button.
On a website that does not provide RSS feed, the icon will be greyed out. Once it detected the presence of a RSS feed, it will be active and you can once again click on it to subscribe to the feed.
