Já estou a usar, apesar da noticia já ter sido dada, deixo aqui outra noticia sobre o mesmo, com uns links porreiros (já tinha postado noutro forum e aproveita-se).
The browser that has taken the internet by storm has just released version 0.9. The new release packs a whole bunch of improvements and new features, including :
# A new default theme, Winstripe (Screenshots 1 and 2)
# A new browser migration tool, allowing you to easily switch to Firefox from IE or Opera
# New theme and extension managers
# Reduced download size
# A new help system
# Improvements in speed and minor fixes
With the new release, Mozilla are also showing off the update features of their products.
Update.mozilla.org
will be a central place for updates to extensions, themes, and the browser itself. With the 0.9 release, Firefox has become 'feature complete' (for a while), and the main improvements between 0.9 and 1.0 will be bug fixes, and stability improvements. For more detailed information on the release, have a look at our interview with Firefox developer, Ben Goodger. If you haven't tried this browser out yet, I suggest you start now.
Update : We've just released out essential guide to Firefox and it's most useful extensions; get it below.
