Download Mozilla Firefox 13.0 Beta 1

As we are used to from Mozilla, the first beta release of the next version has already appeared shortly after the release of the final of the Firefox web browser. New in version 13 includes a new home page when a new tab is opened, similar to speed dial in Opera. Furthermore, a user profile can be cleaned up by creating new and migrating old data and there is tabs on demand. This will only load tabs saved from an old session when clicked. Below is the complete overview of the improvements that we can expect in version 13.0.

New:

• When opening a new tab, users are now presented with their most visited pages
• The default home page now has quicker access to bookmarks, history, settings, and more

Changes:

• SPDY protocol now enabled by default for faster browsing on supported sites
• Restored background tabs are not loaded by default for faster startup
• Smooth scrolling is now enabled by default

Developer:

• 72 total improvements to Page Inspector, HTML panel, Style Inspector, Scratchpad and Style Editor
• the column fill CSS property has been implemented
• Experimental support for ECMAScript 6 folder and set objects has been implemented
• Support for the CSS3 background position property extended syntax has been added
• the :invalid pseudo-class can now be applied to the element
• The CSS turn unit is now supported

Known Issues

• If you try to start Firefox using a locked profile, it will crash (see 573369)
• For some users, scrolling in the main GMail window will be slower than usual (see 579260)
• Some synaptic touch pads are unable to vertical scroll (see 622410)
• Windows: The use of Microsoft’s System Restore functionality shortly after updating Firefox may prevent future updates (see 730285)
