The Mozilla Foundation has released Firefox 1.5, the latest version of the web browser.

Firefox 1.5 is already available now from its own website or from Mozilla's new website.

Mozilla had previously released three test release candidates of the browser, as well as two beta versions, the first in September and the second in October.

The new version includes a wizard that allows users to report websites that don't work in Mozilla's browser so developers can ensure sites working in IE also work in Firefox. It also includes more descriptive error-message pages and a redesigned Options/Preferences window that increases the number of category icons and moves them from the left side of the window to the top.

Other new features in the browser include an automatic software update mechanism, faster navigation using the "Back" and "Forward" tabs, and the ability for users to drag and drop browser tabs for reordering.

Developers also have fortified Firefox 1.5 with new support for web standards, adding support for Scalable Vector Graphics (SVG), JavaScript 1.6 and new versions of CSS (Cascading Style Sheets). SVG is a language based on XML for writing two-dimensional graphics, and JavaScript 1.6 is the latest version of the scripting language.

In addition, the Firefox update adds better pop-up blocking and a host of security enhancements, according to Mozilla. Other new features include the addition of to Firefox's list of search engines and a Clear Private Data function that allows users to quickly remove personal data through a menu item or keyboard shortcut.
