The Firefox feature is similar to the RSS Reader that you are using.

You can setup a Live Bookmark, which is a feed placed in the Firefox bookmarks. It is updated when a new feed is created.
This is the same as the reader you are using, just without the user interface.

You can read more about the RSS Feed Reader along with other Firefox features, on the Firefox features page. ^{(Go There)}

Thanks ComputerWhiz - much appreciated.

To confirm, unless a user preference, there are no major differences between the Firefox RSS Feed Reader and Feedly?

I am not massively techie so keeping it easy is best for me so assume just have the Firefox one?

What do you think?

Thanks in advance

Really, most RSS readers are the same.

In the past I have used the Firefox RSS reader to setup live bookmarks.
Currently I use the RSS Icon In Awesombar add-on. It functions the same as the default Firefox feature, but to save space I want the button in the location bar.

You can use whatever one you want. As said above, it really doesn't matter.

Brilliant!

Thanks for all your help ComputerWhizz!

I'm glad that I could be of some to you.
Thank you for using the Mozilla support forums.
I hope that you will continue to use Firefox and other Mozilla products.
