Gran Paradiso is the provisional name for the new project of the creators of
Mozilla Firefox, and that has the aim of being the germ and the seed for future generations of the popular web browser.
Gran Paradiso uses the Gecko 1.0 engine, and the virtue for users is the spectacular page loading speed. There are other, more technical and less comprehensible improvements for the majority of users.
They have re-written a large part of the code, there is compatibility with API Web Apps 1.9, it includes new values for CSS 2.1, and a large etc. Interesting to get an idea of what we can expect from the new Mozilla browser.
