Download New Firefox 11 For Windows, OS X & Linux


Mozilla has released new popular open source Web browser Firefox 11 . The update brings several new user-facing features and a number of technical improvements.

When Firefox 10 was released in January 2012, the browser gained a new suite of tools for Web developers. Mozilla continued to work on the browser's integrated development tools and has issued several major improvements in Firefox 11. One of the most significant new tools for Web developers is a new Style Editor.



The editor has a two-pane view that allows users to browse all of the inline and external stylesheets associated with a Web page. The right-hand pane will display the selected stylesheet as plain text with syntax highlighting. When the user modifies the stylesheet, the changes will be reflected on the Web page as the user types.
