Three years have passed since the release of Firefox 3, three years of conquer, placing Mozilla's web browser as the second most widely used browser. With approximately 30% of worldwide usage, Firefox follows the all time winner Internet Explorer. The release of Firefox 4 marks the end of a successful era, and the beginning of a new war against its major competitor Internet Explorer 9. Probably as a response to last week's major release from Microsoft, Mozilla decided to reveal faster than expected its new web browser. Therefore Firefox 4 is now available for download and ready to be used by user's worldwide.

Mozilla Firefox 4.0.1.0. Mozilla Firefox browser is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google.

Based on the Gecko 2.0 engine, Firefox 4 comes with many inside changes and new additions. Most important, the new version includes support for HTML5, and CSS3, graphics acceleration with Direct2D and Direct3D on Windows, XRender on Linux and OpenGL on Mac, a new Javascript engine (JaegerMonkey) and a better cross platform component model that supports multiple language bindings. A remarkable job has been done for the Add-on Manager, that stands out now as a separate module with its unique window. From here you can easily stay in touch with the community's new add-ons, but you can also download, install or remove any extensions to the browser. On the downside the download manager has been unaltered and stays identical to the one from Firefox 3.
For a better user-friendly experience, version 4 comes with a revamped interface significantly improved that features a “touchy” character compared to the one present in IE 9. Probably this feeling is the result of a minimalist approach used by Mozilla team to re-design the interface but also because Firefox 4 supports now multi-touch displays. At a first glance you will realize that the browser lacks of any toolbar, all the major command buttons being re-allocated in a single-button menu component. All the tabs have been moved on top of the address bar, making the browsing experience much easier. But the overall design concept looks almost identical to the one present in Opera 11. The only difference is the group tab manager from where you can arrange in any order the opened web-pages by just drag'n'drop them and even save any group of tabs for further usage.
Mozilla improved even further the mobility aspect of their browser and included the Firefox Sync option that allows the user to save and re-use his own settings, passwords, bookmarks, history, open tabs, across other PC's or mobile devices. You just have to create an account on the Firefox Sync official server, choose the settings you want to be synchronized and add the device you want. Another important addition is the Web Console (very similar to what Firebug was for version 2 and 3), from where you can peek into the code of dynamic web pages.
The browsing speed in Firefox 4 is significantly increased, and this can be seen while scrolling complex web pages. Similar to IE 9, with Firefox 4 you can now experience uninterrupted browsing. In case plugins such as Adobe Flash, Apple Quicktime or Microsoft Silverlight will crash on a web page, this will no longer affect the entire browser activity. You can further browse web pages, while you have others opened and completely crashed. If you want to re-establish the connection on a crashed web-page just refresh the page. In case you want to browse on another person's computer and you don't want to leave traces of your web activity, you can start a Private Browsing session. In this way, Firefox will not record the history of your present activity.
Version 4 provides improved security while browsing thanks to HSTS support (HTTPS Strict Transport Security), through which a web-page can request the browser to access its content through HTTPS protocol. In this way any attackers have no access to any important data that might leak while browsing insecure.
Firefox 4 relies heavy on memory resources as previous versions and in time it might become overwhelming for weaker PC systems. Also sometimes it stutters while loading for the first time a web-page with no reason. But I guess this is the price Firefox 4 has to pay being at the moment the most comprehensive browser on the market.
Pluses: faster than previous versions especially on complex web-pages, support for HTML5, and CSS3, fast graphics acceleration, crash protection, OpenType font features, support for WebGL, multi-touch support, Firefox Sync option;
Drawbacks/flaws: heavy on resources, some stuttering loading times while opening for the first time a web-page, no changes in the download manager, interface design based on Opera 11;
In conclusion: With Firefox 4, the Mozilla team has achieved its goal in creating the most comprehensive browser on the market without losing its open-source character.

An early development preview of the next major iteration of Firefox features graphical user interface elements specific to the GUI overhaul planned for the evolution of the open source browser. Mozilla has made available for download a nightly build, namely pre-Alpha 5 for Firefox 4.0(although still labeled v3.7), a release that is tailored to Windows Aero in Windows 7 and Windows Vista, but that also sports changes illustrative of the UI redesign planned for the successor of Firefox 3.6. While Firefox 4.0 pre-Alpha 5 is indeed available for download from Mozilla, users must understand that the release is aimed at early adopters and is designed for testing, and not to be run in production environments or as a fully fledged browser.

Mozilla is currently making its way to the first Beta development milestone of Firefox 4.0, however, it’s not quite there yet. Essentially, the browser vendor intends to produce a Developer Preview of the next major version of its open source browser, ahead of the Beta. In mid-May, the first nightly builds of Firefox 4.0 Developer Preview became available for download and testing. At that time, Mozilla was yet to introduce the new UI elements. This detail has obviously changed since.

Early adopters might recall that Mozilla offered a Firefox 3.7 Alpha Build, back before 3.7 was melted into Firefox 3.6.4, that featured Aero support in Windows 7 and Vista, complete with Glass effects. The facelift synonymous with Firefox’s GUI being tailored to Windows Aero in terms of transparency and translucency, as well to Microsoft’s Ribbon/Fluent GUI, is however reserved for version 4.0, and won’t make it into v3.6.4.

But just because this release of Firefox 4.0 pre-Alpha 5 does bring to the table the evolution of the graphical user interface for the browser, albeit incomplete as it might be, it doesn’t offer a guarantee that it will make it into the Developer Preview or the Beta builds in its current form. Mozilla is hard at work on advancing Firefox on many levels, both under the hood and on the surface, and plans for the redesign were more ambitious than Firefox 4.0 pre-Alpha 5 lets to be seen.

One aspect of the GUI that does appear to have gained some consistency is related to the positioning of the Tabs. Firefox 4.0 pre-Alpha 5 allows users to right-click on the Menu area and select to have the Tabs positioned either above the Address Bar or below, their traditional position. The options to hide the Menu and Toolbar bars contribute to increasing the real estate screen space dedicated to browsing. Additional details of the GUI redesign that users are bound to notice are the new buttons for common actions such as Back, Forward, Home and Reload. What continues to be missing is the implementation of the Ribbon/Fluent style Menu, similar to Opera 10.5, Office 2007/2010, and Paint in Windows 7.
