Need help watching your feed subscriptions in Google Reader? 
The Google Reader Watcher add-on for Firefox is here to help.  With this extension, you can be instantly notified when your favorite new source, blog or any other web site with an RSS feed is updated and ready to read in Google Reader. 

Now I know many people don’t like pandering to the audience for things, however I do want to let you all know it is really easy to follow Firefox Facts in a number of different ways. 
Subscribe via RSS
All you have to do to subscribe to the RSS feed is click that orange icon in the Firefox address bar.

You will then be given many different options in which you can subscribe to the feed.  You can set it up [...]

Not sure how closely you are following Internet Explorer 8 development, but they do have one cool new feature called Web Slices.  This will let you subscribe to only a section of a web page, and easily delete them when they are no longer needed.  You can now use this Internet Explorer 8 feature of the future now in Firefox.
WebChunks is a Firefox 3’s implementation of Microsoft Web Slices.  It allows you to “follow” an area of a web [...]

There have been a number of RSS feed extensions out there that turn Firefox into a syndication master. You can go from browser to RSS reader and back within the blink of an eye – and not have to worry about launch a new web site or a new program.

One new extenion RSS feed reader that recently caught my eye was Beatnik. It promises to be a “simple but elegant news reader”. With a description [...]

With the release of Firefox 2, the browser has done a much better job with handling RSS feeds.

For an example, let’s use the RSS feed for Firefox Facts:
http://feeds.feedburner.com/firefoxfacts
Now when you launch that in Firefox, you will be given a clean [...]

The folks over at Lifehacker have been up to it again with creating yet another cool extension for Firefox.
Firefox only: Google Reader is one of the best web-based feed readers out there, but it could stand a few adjustments. Greasemonkey scripters have come up with a few Google Reader user scripts that make some welcome GReader tweaks like maximizing the viewing area, skipping Google’s default subscribe mechanism, and adding keyboard shortcuts.
I downloaded it the minute I saw it [...]

If you use Google’s Feed Reader this is a Greasemonkey script that you need. This script adds a feed icon to the upper right corner of your browser window for one-click subscription to Google Reader.
My version of the script adds an overlayed check icon when you’re subscribed to at least one of the feeds that the site advertises via auto-discovery. This was made easy by a URL that Reader exports: http://www.google.com/reader/api/0/subscribed?s=feed/. It returns “true” or “false” depending on whether [...]
