Alternative to Endnote?

Power Firefox users may be familiar with some of the vast range of extensions that are available for this program. These extensions allow third parties to add new functionality which the Firefox developers may not have thought of or considered important. You can find out about the range of extensions here.
An extension that definitely has use in is the Zotero extension. This Extension allows you to collect manage and cite your research sources. It doesn’t offer the full functionality of Endnote, but its list of features include:

• Automatic capture of citation information from web pages
• Storage of PDFs, files, images, links, and whole web pages
• Formatted citation export (style list to grow rapidly)
• Integration with Microsoft Word
• Runs right in your web browser

It currently only supports a small number of the major citation styles, such as MLA and Chicago, but this should improve with time. Also as it’s an Open Source product it’s free.
