Over on NoahBrier.com, he posted a good summary of the advantages of using Firefox for readings blogs. Of course, its not only good for blogs, but for any web browsing. Firefox has definitely improved my web experience.
I’d like to add one more extension suggestion to what Noah lists, which will enhance your RSS experience even further:
This extension enhances RSS reading. I absolutely love this extension. It displays your RSS feeds, which you place in a bookmark folder specified in Sage preferences. It keeps track of which RSS entries you have read. Its divided into two segments, the top segment showing the RSS feeds, and the bottom segment showing you the entries for each RSS feed as you click on it. You can mark them read w/o reading them, mark all entries, read, read the summary of an entry by hovering over it, and then read the entire entry in the current window, a new window, or a new tab.
