Research Made Easier with Zotero

I find that Zotero, the Firefox add-on, drastically speeds up the research process for me. It allows me to save articles to read or cite at a later time. It automatically pulls must of the information needed for citations, and makes it easy to add the rest of the information. It creates citations in most of the popular styles (MLA, APA, etc.), and allows you to create an entire bibliography. Research can often be an arduous process, but Zotero helps keep everything together, thus lightening the load a bit. The new beta version allows you to synchronize or share your data. You won’t have to worry about losing that citation, which can be a real pain.

Do you use Zotero, or another similar program? What is your experience?
