1. Easier downloads. While the older Download Manager was quite serviceable, Mozilla has made some nice tweaks in the new version. It now lists not only the file name, but the URL it was downloaded from, and includes an icon that leads to information about when and where you downloaded it. (The Remove link has been, well, removed from the Download manager -- you now have to right-click to delete a listing.)
2. An enhanced address bar. Mozilla has also made improvements in the autocomplete function of its address bar (which Mozilla calls a "location bar"), and I have to say I find it both impressive and useful. In Firefox 3 Beta 2, the autocomplete doesn't just offer a list of URLs that you've been to, but includes sites that are in your bookmark list.
3. A workable bookmark organizer. Speaking of bookmarks, the separate history/bookmarks sidebars and managers have been replaced or, rather, augmented by a single Places Organizer, which uses Windows Explorer's familiar tree-on-the-left/list-on-the-right format. It offers a simple, quick way to read and manage your history and bookmarks including the ability to immediately edit a bookmark's name, location and tags rather than having to go into the Properties box .
4. Easier bookmarking. There are, in fact, quite a few new features involving bookmarking, some of which are small but highly useful. For example, you can now quickly create a bookmark by double-clicking on a star that appears in the right side of the address bar. You can also add tags to your bookmarks, which could work nicely as an organizational tool.

There is also new folder called Smart Bookmarks in the toolbar. It offers three categories of bookmarks Most Visited, Recently Bookmarked and Recent Tags and is automatically populated during the course of your Web sessions. Since, like most people, I have a series of sites that I tend to visit regularly, I can see how something like the Most Visited list could prove handy as a one-click resource for my daily surfing.
5. Better memory management. I'm a great fan of Firefox, but there have been times when I've considered going back to Internet Explorer because of issues I was having with memory. After a couple of hours of adding and dropping tabs, Firefox could commandeer nearly 200MB of memory, at which point I'd usually have to shut it down to prevent my other apps from grinding to a halt.
