This is both an easy and difficult question. It’s easy because every Firefox user lists their favorites and their newest finds on their site (assuming they have one). Of course, not everyone has a blog but searching the blogosphere is one way to go. Of course, the difficult part is that information or should we say, add-on/plug-in overload can set in quickly.
So, no what can you do? How about going to the source? The Firefox add-on (aka extension) site allows users to sort/view add-ons by:
+ Popularity
++ RSS Feed
+ Last Update
++ RSS Feed
+ Sort by Name
++ RSS Feed
