Zotero, a research extension for Firefox

I stumbled upon an amazing research tool toady while I was searching for a download management Firefox extension today.  Zotero is more than just a download tool.  It is a literary reasearch tool which allows you to track web citations, bookmarks, and the like from within the browser.  I would traditionally create a Bookmark folder and dump links into it until I fealt I had enough to write a post.  However, with Zotero, all my notes, bookmarks, and files from the web are stored inside a project file that my browser stores.  I cannot comment enough on the professionalism that went into this extension.    Unlike the usual extensions that do little tricks for you (downloading YouTube videos for example) this one is an actual productivity tool.  I hope this is a sign that more professionals are seriously moving to open source software development.
