Firefox 3 itself has thus far been indistinguishable from the Release Candidate 3 build I've been using for a week or so. I expect there was some last-minute tweaking and polishing, but no surprises for thise of us who switched to the Firefox 3 betas and release candidates some time ago.
Firefox 3 is based on the Gecko 1.9 Web rendering platform, which has been under development for the past 31 months. Building on the previous release, Gecko 1.9 has more than 14,000 changes including some major re-architecting to provide improved performance, stability, rendering correctness, and code simplification and sustainability. Firefox 3 has been built on top of this new platform resulting in a more secure, easier to use, more personal product with a lot more under the hood to offer website and Firefox add-on developers. Suffice to say, Firefox 3 is fast - very fast - and in the same ballpark inhabited by other speedster OS X browsers like Opera 9.50 and SAfari 3.
If you're coming from Firefox 2, Firefox 3 for Mac has a much-improved and more attractive user interface with a more native Mac OSX look, smaller buttons, more compact tabs, and new forward/back buttons that debuted in the Windows version of beta 3. I like the new Firefox interface a *lot* better thabn the old one, but I still think Opera (especially with its flash new interface introduced with the version 9.50 final release last week) and iCab, and even the Japanese Webkit based browser Shiira, have the edge. One thing I'm not taken with is Firefox's tiny page load progress Barquentine Ventures Newsfeatures at the bottom of the window. I've gotten used to progress bars at the top, a la Safari and Opera.
Also new iis one-click site info. JUst click the site favicon in the location bar, and an information dialog appears.
If that doesn't provide enough info., click the More Information button and a window appears with 4 tabs containing a whole raft of data pertaining to the page you're on, allowing you to check if your connection is protected from eavesdropping. Identity verification is prominently displayed and easier to understand. When a site uses Extended Validation (EV) SSL certificates, the site favicon button will turn green and show the name of the company you're connected to.
Firefox 3's location bar autocomplete now looks on visited and bookmarked page titles and tags as well as web addresses, and highlights which parts of the page title and/or URL match the entered text. Results for autocomplete are shown in two lines: one for page title and the other for web address, and in contrasting colors making it easier to isolate one or the other depending on what you're looking for. Also, matched terms are highlighted to direct attention.
The Smart Location feature incorporates an improved search algorithm that “calculates the recency and frequency” of sites visited to help yield search results of highest relevancy. You can also associate keywords with bookmarks to sort them by topic.
The downloads manager has also been improved (although I still think Opera has the best downloads manager in the business), with support for searching through previous downloads, resuming downloads between sessions, and it now displays the domain of the source site next to each completed download. The Places feature, which organizes bookmarks and browser history, has also been enhanced, offering improved search functionality and a new Smart Bookmarks folder on the Bookmarks Toolbar.
It is now possible to search History, tags and bookmarks with a real, configurable search interface, and the Mac OS X version of Firefox 3 now has full support for native widgets in forms.
Probably my favorite new feature in Firefox 3 is that before shutting down Firefox puts up a dialog asking if you want to save the contents of tabs in your current browsing session. In most instances I definitely do, and the icing on the proverbial cake is that the tabs get reloaded from the cache, which no longer gets dumped on shutdown if you choose the save option with satisfying dispatch upon starting the program again. This is a big enhancement from Firefox 2's ability to remember the contents of tabs after program crashes.

Reportedly, Firefox 3.0's memory demands (especially its notorious memory leaks of which some 350 have reportedly been plugged) have been "dramatically improved," and it does seem like a better citizen on my Desktop than earlier versions,
Here are some more Firefox 3 improvements:
More Secure
* One-click site info: Click the site favicon in the location bar to see who owns the site and to check if your connection is protected from eavesdropping. Identity verification is prominently displayed and easier to understand. When a site uses Extended Validation (EV) SSL certificates, the site favicon button will turn green and show the name of the company you're connected to.
* Malware Protection: malware protection warns users when they arrive at sites which are known to install viruses, spyware, trojans or other malware.
* New Web Forgery Protection page: the content of pages suspected as web forgeries is no longer shown.
* New SSL error pages: clearer and stricter error pages are used when Firefox encounters an invalid SSL certificate.
* Add-ons and Plugin version check: Firefox now automatically checks add-on and plugin versions and will disable older, insecure versions.
* Secure add-on updates: to improve add-on update security, add-ons that provide updates in an insecure manner will be disabled.
* Anti-virus integration: Firefox will inform anti-virus software when downloading executables.
* Vista Parental Controls: Firefox now respects the Vista system-wide parental control setting for disabling file downloads.
* Effective top-level domain (eTLD) service better restricts cookies and other restricted content to a single domain.
* Better protection against cross-site JSON data leaks.
Easier to Use
* Easier password management: an information bar replaces the old password dialog so you can now save passwords after a successful login.
* Simplified add-on installation: the add-ons whitelist has been removed making it possible to install extensions from third-party sites in fewer clicks.
* New Download Manager: the revised download manager makes it much easier to locate downloaded files, and you can see and search on the name of the website where a file came from. Your active downloads and time remaining are always shown in the status bar as your files download.
* Resumable downloading: users can now resume downloads after restarting the browser or resetting your network connection.
* Full page zoom: from the View menu and via keyboard shortcuts, the new zooming feature lets you zoom in and out of entire pages, scaling the layout, text and images, or optionally only the text size. Your settings will be remembered whenever you return to the site.
* Podcasts and Videocasts can be associated with your media playback tools.
* Tab scrolling and quickmenu: tabs are easier to locate with the new tab scrolling and tab quickmenu.
* Save what you were doing: Firefox will prompt users to save tabs on exit.
* Optimized Open in Tabs behavior: opening a folder of bookmarks in tabs now appends the new tabs rather than overwriting.
* Location and Search bar size can now be customized with a simple resizer item.
* Text selection improvements: multiple text selections can be made with Ctrl/Cmd; double-click drag selects in "word-by-word" mode; triple-clicking selects a paragraph.
* Find toolbar: the Find toolbar now opens with the current selection.
* Plugin management: users can disable individual plugins in the Add-on Manager.
* Integration with Vista: Firefox now has Vista-specific icons, and uses native user interface widgets in the browser and in web forms.
* Integration with the Mac: the new Firefox theme makes toolbars, icons, and other user interface elements look like a native OS X application. Firefox also uses OS X widgets and spell-checker in web forms and supports Growl for notifications of completed downloads and available updates. A combined back and forward control make it even easier to move between web pages.
* Integration with Linux: Firefox's default icons, buttons, and menu styles now use the native GTK theme.
More Personal
* Star button: quickly add bookmarks from the location bar with a single click; a second click lets you file and tag them.
* Tags: associate keywords with your bookmarks to sort them by topic.
* [Improved in Beta 4!] Location bar & auto-complete: type in all or part of the title, tag or address of a page to see a list of matches from your history and bookmarks; a new display makes it easier to scan through the matching results and find that page you're looking for. Results are returned according to their frecency (a combination of frequency and recency of visits to that page) ensuring that you're seeing the most relevant matches. An adaptive learning algorithm further tunes the results to your patterns!
* Smart Bookmarks Folder: quickly access your recently bookmarked and tagged pages, as well as your more frequently visited pages with the new smart bookmarks folder on your bookmark toolbar.
* Places Organizer: view, organize and search through all of your bookmarks, tags, and browsing history with multiple views and smart folders to store your frequent searches.
* Web-based protocol handlers: web applications, such as your favorite webmail provider, can now be used instead of desktop applications for handling mailto: links from other sites. Similar support is available for other protocols (Web applications will have to first enable this by registering as handlers with Firefox).
* Download & Install Add-ons: the Add-ons Manager (Tools > Add-ons) can now be used to download and install a Firefox customization from the thousands of Add-ons available from our community add-ons website. When you first open the Add-ons Manager, a list of recommended Add-ons is shown.
* Easy to use Download Actions: a new Applications preferences pane provides a better UI for configuring handlers for various file types and protocol schemes.
Improved Platform for Developers
* New graphics and font handling: new graphics and text rendering architectures in Gecko 1.9 provides rendering improvements in CSS, SVG as well as improved display of fonts with ligatures and complex scripts.
* Color management: (set gfx.color_management.enabled on in about:config and restart the browser to enable.) Firefox can now adjust images with embedded color profiles.
* Offline support: enables web applications to provide offline functionality (website authors must add support for offline browsing to their site for this feature to be available to users).
* A more complete overview of Firefox 3 for developers is available for website and add-on developers.
Improved Performance
* Speed: improvements to our JavaScript engine as well as profile guided optimizations have resulted in significant improvements in performance. Compared to Firefox 2, web applications like Google Mail and Zoho Office run twice as fast in Firefox 3 Beta 4, and the popular SunSpider test from Apple shows improvements over previous releases.
* Memory usage: Several new technologies work together to reduce the amount of memory used by Firefox 3 Beta 4 over a web browsing session. Memory cycles are broken and collected by an automated cycle collector, a new memory allocator reduces fragmentation, hundreds of leaks have been fixed, and caching strategies have been tuned.
* Reliability: A user's bookmarks, history, cookies, and preferences are now stored in a transactionally secure database format which will prevent data loss even if their system crashes.
