According to a press release from the company Recap, it has created a free extension for Firefox that improves the experience of using PACER, the electronic public access system for the U.S. Federal District and Bankruptcy Courts.  PACER contains the docket sheets and many documents filed with the federal courts.

The press release states: "RECAP is an extension to the popular Firefox web browser that gives PACER users a hassle-free way to contribute to a free, open repository of federal court records. When a RECAP user purchases a document from PACER, the RECAP extension helps her automatically send a copy of that document to the RECAP archive. And RECAP saves its users money by notifying them when documents they’re searching for are already available for free from the public archive."
