Zotero is free, open-source bibliographic software. Bibiliographic software "collects, manages, and creates citations for your research." Download Zotero as a Firefox browser extension, and it will be available everytime you open Firefox on your computer.
If you use serveral computers, the best way to access your Zotero Library is to sync your libraries automatically via the Zotero server. See Zotero's Syncing Documentation for more information.
Another option for accessing Zotero on multiple computers is to download a copy of Firefox to your portable zip drive and use that copy of Firefox with whatever computer you access. See Portable Firefox for more information.
