Firefox 3.0 alfa 3

Los desarrolladores de la Fundación Mozilla liberar la tercera versión alfa de la futura versión 3.0, "Gran Paradiso".

La próxima versión, conocida bajo el nombre clave de "Gran Paradiso", ya tiene su tercera alfa disponible.

Destaca sobre todo de la misma la migración al motor Gecko 1.9, (Firefox 2 está basado en Gecko 1.8.1).

Se trata de una versión inestable, en principio tan solo destinada para desarrolladores y pruebas.

No obstante es una versión considerada de gran importancia para los desarrolladores de la Fundación Mozilla y cuyo lanzamiento está previsto para el segundo trimestre de 2007.

Changelog:
* Animated PNG (APNG) images are now supported.
* The DOM clientLeft and clientTop attributes are now supported.
* Introduced support for , which puts resources into the browser´s offline cache. This allows a web application to ensure that its resources are available in the cache when the browser goes into offline mode. See Marking Resources for Offline Use for further details on offline support.
* Improved precision of layout and scaling across a wide range of screen and printer resolutions.
* Implemented cycle collection in XPCOM, which detects cases where two released objects hold one another, but neither is held by anyone else. In this scenario, both objects can safely be purged. Previously, the holds each has on the other would have prevented them from being purged.
* Added support for the HttpOnly cookie attribute, which marks a cookie as readable only by the server and not by client-side scripts.
* Added a new preference, "Warn me when web sites try to redirect or reload the page", which notifies the user when the page specifies HTTP-EQUIV=refresh.
