What do you think the new version of Firefox 6.0

What do you think a copy of the new Firefox browser version 6.0
Is it better than version 5.0
From the experiences of some developers and users of the web version of the proposed new features after the test
It's a fast browsing and takes up less space in the memory and quick to take off in the system
Version found on the company servers Mozilla Firefox before the official release in three days which makes you able to download the version and try it now

well so far firefox 6 is good it really works for me and easy to use especially in browsing the internet and mozilla is my first choice rather than anything.
