Mozilla Firefox 18 Download

Download the latest version of Mozilla's Firefox

Firefox users who cannot wait to update the stable channel of the web browser from version 10 to 11, can download the new version from the official Mozilla ftp server or third party download sites early. Please note that while it is unlikely that the final version will get replaced in last minute, it has happened in the past. It is recommended to wait for the official release announcement if Firefox is running in a productive environment, or if you do not need to have access to the new feature set introduced in the browser right away.

The majority of features are only interesting for web developers and developers in general. Firefox 11 supports the CSS text-size-adjust property, and the outerHTML property. Developers can furthermore make use of the Style Editor for editing CSS, and the new Page Inspector 3D View which is available if the computer is compatible with WebGL.Firefox 11 furthermore supports the SPDY protocol for faster page loads, and XMLHttpRequest HTML parsing.The change log lists unresolved issues, among them some that have been noticed by some users in previous versions of the browser as well. This includes the slow scrolling in the Gmail window, or jerky scrolling and text input under certain conditions.It is not really necessary to update the browser right now, instead of waiting the three days before the official announcement is being made. It would be different if stability or security updates were included in the release.
