Firefox 3 and Ajax

Firefox 3 is available for download on Mozilla's website (see resources at bottom ). It integrates the Gecko 1.9 engine and the Cairo renderer. It provides many new functions to facilitate browsing the Internet.


Innovations in Firefox 3

The browser is closer to standards of the Web defined by the W3C. It is assured that it will be able to pass the Acid2 compatibility test. But the comfort of use and the functionalities are also improved of course.

A better display

Gecko 1.9, the new rendering engine accelerates the display of all components of Web pages. And the graphic engine Cairo adds to Firefox what one greatly appreciates since Internet Explorer 7, a better processing of anti-aliasing, for perfectly smoothing of characters, which look very clean now and faster.
All types of media, graphics and others, are recognized and played, provided the codecs are present on the computer. Plug-ins such as Flash, WMV, Java will be better taken into account.
The addition of missing plugins will be facilitated. That could profit to Silverlight, the concurrent technology from Microsoft except that Firefox supports the Canvas element that makes HTML 5 an alternative to Silverlight.

The news for Navigation

Here is the list of improvements made by Firefox, such as exposed in the Field Guide to Firefox 3 by Debra Lynn Richardson:

Plugin manager

- The "Get Addon" will choose among recommended addons.
- It is possible to manage plugins, disable them, which should be managed by the plugin itself with the version 2.
- If a security vulnerability is found in a plugin, it is automatically deactivated.

Extended bookmark manage

To simplify the management of bookmarks, Firefox 3 introduces several functions: star, dialog, tags and smart folder.
- Stars: In the URL bar you see a star on the right, just click on the star to add the page to bookmaks.
- Dialogue: The box edition has been expanded with the possibility of creating a category on the fly (as on Wordpress).
- Tags: It is close here also to Wordpress, creating tags to categorize a page and to find pages in a list for each tag.
- Smart folder: The folder is smart when page are added automatically to it. Whenever you add to your favorites a new page, if it contains the keywords of a folder in the title or either in its tags, the page is added to the folder with these keywords.

Smart location bar

In addition to the icons added, the URL bar itself has a very important new function. Previously, when we began to type, a function completr the URL providing it has already been visited. This function goes further. Simply type in keywords to see the URLs that contain them, or the pages whose title contains them, and this together with additional information regarding navigation in a drop-down list enriched by icons.

Password Management

A much anticipated feature, the management of passwords.
- New dialog, which is not modal, it remains displayed when you visit the site, which helps decide later, after verifying that the password typed is the right one (Firefox 2 stores a bad password and then retains it!)
- The manager of passwords is also more developed with search function and filter.

Download

- Interrupted or paused download may be resumed later.

Gecko and rendering

- Improvements in CSS. See Mozilla.
- About DOM, extensions of Internet Explorer are now supported by Firefox (onCopy, onPaste ...).
- The colour profiles can adjust the colors depending on the color management of the graphics card.
- The Cairo graphics engine included in Gecko draw better fonts as does IE7 too.

Zoom

It is possible to enlarge the page or just the text. This is remembered by the browser and reused the next time you view the page.

HTML 5

- The new DOM method, getElementsByClassName() is recognized by Firefox 3.
- The "DOM 5" method window.postMessage() is added. For sharing data between different protocols.
- Canvas, which allows you to draw on a web page and make graphical interfaces, adds two functions provided in HTML 5: transform() and setTransform(). However the new functions of text seem specific to Firefox.
- The offline event management is implemented.

Cosmetic improvements

- History keeps now favicons and a scroll bar appears on the menu.
- The tabs slip under the mouse from left to right, for immediate access to the pages.
- A wide range of themes is provided, you can see some examples. The themes are very different and there is no difficulty to find something to your taste!

Foreign Languages

- The URL bar now supports UTF-8 which can display accents and special characters.

Security

- Malware sites are blocked from a list to which the browser has access.
- Security with CardSpace and OpenID integrated. To avoid phishing the fact that an evil site can pretend to be a financial site and recover your passwords, management of OpenID is integrated into the browser.
- Ability to surf privately without leaving traces, such as the contents of the buffer.
- Icon identification site in the navigation bar to the left of the URL. This button can display data on a site.

Performances

This new version is much faster than the previous one and it goes up to nine times the speed of IE7. The memory is also used more economically.

Features various

- Recognition of microformats for providing information on the information.
- Saving a page as a PDF file.
- Linking documents to web services, as binding on a file to a program according to its format (doc with Word, for example).
- Parental control included.
- A more efficient printing manager, able to adapt the size of pages to the paper, to avoid splitting words or paragraphs.
- The software is provided in the form of MSI installation file for Windows.

The release of Firefox 3 is planned for June 17 2008.
