The Web is all about innovation, and Firefox sets the pace with dozens of new features to deliver a faster, more secure and customizable Web browsing experience for all.
User Experience. The enhancements to Firefox provide the best possible browsing experience on the Web. The new Firefox smart location bar, affectionately known as the "Awesome Bar," learns as people use it, adapting to user preferences and offering better fitting matches over time.
Performance. Firefox is built on top of the powerful new Gecko platform, resulting in a safer, easier to use and more personal product.
Security. Firefox raises the bar for security. The new malware and phishing protection helps protect from viruses, worms, trojans and spyware to keep people safe on the Web.
Customization. Everyone uses the Web differently, and Firefox lets users customize their browser with more than 5,000 add-ons.
What's New in Firefox 11
Sync Addons across machine.
The most exciting features coming with Firefox 11 is that you can get a real personalized web browsers including Addons, bookmarks, browser historys, while in previous version, Firefox allows you to save bookmarks, saved passwords only into remote server for sync among different devices. Wherever you are, you can get your own firefox with your firefox account.
Import bookmarks from Chrome
Web browsers become more and more open to all of partners, even competitors. To make it easy to shift between multiple browsers, firefox 11 allows you to import data including bookmarks, saved passords and more from Google Chrome to Firefox.
By the way, for developers, there also a cool new option to visualize code in 3D known as 3D Page Inspector View or "Tilt" plus an on-the-fly CSS editor. Anyway, I think most of you will not care about this features. so just forget it.
What's new in Firefox 6
Mozilla claim the new browser is 20% faster than Firefox 5 (which wasn’t particularly slow). The speed gains will also be evident to Linux users.
Panorama is Firefox’s tab grouping system. I had a few initial reservations but I now love the feature and use it extensively. Firefox 6 loads inactive groups on demand — it improves start-up times and reduces memory usage.
Firefox 6 highlights a site’s domain in the address bar (sorry Mozilla, I still can’t bring myself to call it the Awesome bar!) It’s a feature present in all competing browsers.
Website Permissions Control
The new Data Management Window allows you to set site-based permissions so the same rules apply to every page within a specific domain. The feature is experimental, but you can access it by entering “about:permissions” in the address bar.
The Scratchpad is similar to Firebug’s console command line, however, it doesn’t require the add-on and allows you to save snippets for later use.
In addition, if you like the Web Console, you’ll be pleased to hear that it can be moved and docked elsewhere.
More HTML5, CSS3 and DOM Loveliness
Web developers will able to adopt the following HTML5 technologies in Firefox 6:
The progress tag for graphical progress bars has been added. Colors can be styled with the ::-moz-progress-bar pseudo-element.
A new -moz-orient property allows you to set some elements, such as progress bars, to horizontal or vertical orientation.
The track element is supported so you can apply text tracks to native audio and video.
CSS3 border-radius can be applied to iframes.
Custom data attributes (data-*) can now be accessed via the DOM’s element.dataset property.
Text decorations such as underlines, overlines and strike-throughs can now be styled in CSS using -moz-text-decoration-line (none, underline, overline, line-through), -moz-text-decoration-style (inherit, solid, double, dotted, dashed, wavy) and -moz-text-decoration-color properties.
The new -moz-hyphens property lets you control how hyphenation of words is handled during line wrapping (none, manual, auto).
The result of a media query string can be evaluated programmatically using the window.matchMedia() method.
Early support for Server-Sent Events has been implemented. This API permits push notifications from the server in the form of DOM events.
Touch event support for touch-sensitive screens and trackpads has been included.
What's new in Firefox 5!
It fixes close to a thousand bugs, and takes care of some serious security issues;
“Do Not Track” - Firefox 5 allows user to surfing online while keep personal data protected in a higher level. User data tracking from websites will prohibited with "Do Not Track" features .
What's new in Firefox 4
New Add-on Manager
Firefox’s new add-ons library has been redesigned to make it easier to find new ones and manage the ones you currently have.
Get to your favorite sites quickly
– even if you don’t remember the URLs. Type your term into the location bar (aka the Awesome Bar) and the autocomplete function will include possible matches from your browsing history, bookmarked sites and open tabs.
The Awesome Bar learns as you use it
—over time, it adapts to your preferences and offers better-fitting matches. We’ve tweaked it to give you greater control over the results (including privacy settings) and increased performance so you find what you need even faster.
Improved HTML 5 for web apps and video
Firefox 4 supports HTML 5 – the newest web page standard. It will let you take advantage of the latest web apps with PC-like functions such as drag and drop and advanced photo editing.
You might be notice the main interface of Firefox has been updated at the first glance. The tabs are changed to above the Awesome Bar to make it easier to focus on the content of the sites you visit.
Better crash protection
Firefox 4 now becomes more stable than ever. If a plug in like QuickTime or Flash crashes in a tab, Firefox 4 will make sure it doesn’t cause the entire browser to crash with it. All you have to do is reload the page.
New added Firefox Button
All your menu items are now found in a single button for easy access. I believe that this updating are learned from Google Chrome.
Simplified Reload/Stop Button
The position of refresh button has been changed. see below, it features one easy button to stop loading pages or reload pages.
Hardware-accelerated graphics for better video
Just like Internet Explorer 9, Firefox 4 uses hardware-accelerated graphics. That means it uses your computer’s processing power to help render video and graphics.
Organize tabs by groups
If you tend to have a lot of tabs open at once, Firefox 4 will help you stay organized with a feature called Panorama. With Panorama, you can create groups of tabs and open them all at once.
Switch between tabs from the URL bar
If you have a lot of tabs open, just start typing the title of the page in the URL bar. An option to switch to that tab will pop up so you don’t have to go searching for it.
Now, download Firefox 4
and enjoy it!
