Yep, it is supposed to be officially announced tomorrow but if you now how to try, you can get the final 2.0 from their website. You want a proof? Here we go, a screenshot:

I like the new layout, icons are smaller, it is a little bit more integrated with MacOS X. Preferences are also improved as well as Extensions/Themes GUI. I really like to be able to restore all my last tabs when I launch Firefox or after a crash.

RSS feeds are also manage in a better way but I still prefer the way it is in Safari. With Firefox, it is very unconfortable to go trough a list of ‘Live Bookmarks’ in your bookmark…I guess it will come for version 3, next year. Beside this, it is worth the upgrade, do it NOW! Not to mention that most of my useful extensions are already compatible:

• Performancing for Firefox (a blog publishing tool),
• Firebug (THE tool for web developers),
• Foxmarks (sync for my bookmarks at home, office and on my usb key),
• Web Developer,
• Selenium IDE,
• DOM Inspector

I used to have Tab X, but it is now part of Firefox (with more features). I do not want to list all new features of Firefox itself because I am sure that you can read about them almost everywhere on the web.
