All new features of firefox 3 ! Have a look ! !

1. One-Click Bookmarking

Manage your bookmarks a lot or a little. One click on the star icon at the end of the location bar bookmarks a site. Two clicks and you can choose where to save it and whether to tag it. File bookmarked sites in easy-to-access folders and organize according to theme (like “job search” or “favorite shopping”). Find your bookmarked sites in a flash by entering the tag, page or bookmark name into the location bar. The more you use your tags and bookmark names in the location bar, the more the system will adapt to your preferences.

2. Smart Bookmark Folders

These dynamic folders give you easy access to your favorite sites and can be placed in your Bookmarks menu or Bookmarks toolbar. We’ve included some for you as defaults, including one that shows you the sites you visit most frequently (create your own by saving your searches in the Library).

3. Improved Memory Management

With all new management functions in place, Firefox 3 keeps memory usage under control. The XPCOM cycle collector continuously cleans up unused memory. Plus, hundreds of memory leaks are now remedied.
* Faster JavaScript
Firefox now empowers even greater Web development, with JavaScript 1.8—including expression closures, generator expression and array reduce.
* Smaller Memory Footprint
Short and sweet, Firefox now uses less of your computer’s memory while it’s running.
* Faster Page Load
A redesigned page rendering and layout engine means you see Web pages faster and in the way they were meant to be seen.
Graphics Engine Improvements

Improved text rendering is just the beginning of the benefits of an all new graphic engine for Firefox 3.

4. Full Zoom

Visit your favorite news page and read the caption under the picture—or view the picture itself in a size you can see. An elegant new zoom feature lets you swoop in and see entire web pages. They scale in the way you’d expect them to, with all the elements of a page’s layout expanding equally, so you can zero in on what matters.
