The replacement name, Firebird, provoked an intense response from the Firebird free database software project. In response, the Mozilla Foundation stated that the browser should always bear the name Mozilla Firebird to avoid confusion with the database software. After further pressure from the database server's development community, on February 9, 2004, Mozilla Firebird became Mozilla Firefox, often referred to as simply Firefox. Mozilla prefers that Firefox be abbreviated as Fx or fx, though it is often abbreviated as FF. The Firefox project went through many versions before version 1.0 was released on November 9, 2004. Firefox uses a sandbox security model, and limits scripts from accessing data from other web sites based on the same-origin policy. It uses SSL/TLS to protect communications with web servers using strong cryptography when using the HTTPS protocol. The Mozilla Foundation offers a "bug bounty" (up to 3000 USD cash reward and a Mozilla T-shirt) to researchers who discover severe security holes in Firefox. Official guidelines for handling security vulnerabilities discourage early disclosure of vulnerabilities so as not to give potential attackers an advantage in creating exploits.
