Don't go downloading the latest version of Firefox just yet.... You might find yourself kicking yourself in the butt when you realize that it is just a beta and you have lost more than your bookmarks.
Mozilla has released Firefox 3 Alpha 5, code named Gran Paradiso, as a way to get some feedback from developers and beta testers. As with most things designated "Alpha", it's not really ready for prime time. New features unfortunately mean that it won't work at all for you Windows 95, 98, ME and Mac OS X version 10.2 users. While we have about 100 reasons you should upgrade your aging operating system, Gran Paradiso isn't one of them.
Regardless of Gran Paradiso's beta status, it does show off "Places," one of the other cool features that will be incorporated once the public version is made available. Places "functionality exists in this release for a new side panel that allows you to control your bookmarks, RSS subscriptions, and browser history in one convenient space." Using the open-source SQLite database, it gives greater extensibility and the ability to backup and restore bookmarks, however, this also means it's incompatible with earlier Firefox bookmarks.
If that weren't enough for you, the beta sports an improved search engine keyword support, a new password manager, Extension Manager, better integration with Mac OS X and FUEL (Firefox User Extension Library).
Unless you are planning on creating your own add-ons, it might be best to wait till Fall 2007 when the public version hits the web.
Ye all have been warned...
