Release notes from Mozilla

The new Firefox 15.0 includes improvements in performance and standards support.

Mozilla has switched Firefox to a rapid release development cycle which means new versions will come more frequently. The non-profit organization has promised to push out a new stable build every six weeks.

* Web developers can now visualize a web page in 3D using the Page Inspector 3D View
* SPDY protocol support for faster page loads is now testable
* XMLHttpRequest now supports HTML parsing
* Files can now be stored in IndexedDB (see bug 661877)

Fixed:
* Websockets has now been unprefixed
* Redesigned media controls for HTML5 video
* Firefox notifications may not work properly with Growl 1.3 or later (691662)

Known Issues:
* Two-digit browser version numbers may cause a small number of website incompatibilities (see 690287)
* 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)
