Amazon.com subsidiary A9.com on Monday released a version of its Internet toolbar for the Firefox Web browser. A9 said the toolbar, which is available for free download, will offer the same features to users of the Mozilla open-source software as it does for other browsers. Those features include the "bookmarks" function, which lets users save favorite Web sites and access them from any PC, and "diary," which lets users save notes to themselves.
Executives at A9 said the company had received a large number of requests from consumers looking for a version of the software to run with Firefox.
